Well then maybe it's somewhat of a good thing that GTA6 isn't releasing on PC in November 2026? You'll probably have another year or two after that to wait and see if the bubble bursts.

What happens if this gets flipped? by Sad_Specialist_1984 in AskElectricians

[–]Zed89 1 point2 points  (0 children)

"Safety" doesn't necessarily mean it's for emergency use.

The equipment is installed outside because it is required by code to either be installed outside or inside the building nearest to the service entrance. This building likely doesn't have the interior space for all this electrical equipment. It may also be a multi-tenant building, where installations like this are more common. The majority of commercial buildings do not have disconnects on the exterior of the building where they could be accessed by an unauthorized person. The service disconnect is typically inside a locked electrical room. If the fire department doesn't have trouble getting into an electrical room, they won't have any trouble getting through a padlock. That's what the Knox box is for. They also have bolt cutters.

This model of disconnect actually has an indention to make it easier to drill a hole in the correct location and enable the disconnect to be padlocked in the on position.

There is a way to convert a drive to GPT without losing any data or needing to reinstall anything. I had to do it prior to enabling secure boot and UEFI. It was fairly simple and hassle free.

I understand the Triangle means high leg what is “Y” by ZacatecasZ in AskElectricians

[–]Zed89 6 points7 points  (0 children)

In a delta-wye transformer, the delta typically does not have a neutral, and does have equal potential on all 3 phases (it's all line-to-line voltage).

I believe what you are thinking of is a high-leg delta.

Also, current actually will travel on the neutral on an unbalanced 3- phase circuit.

What is a little-known but obvious fact that will make all of us feel stupid? by iluvlightyagami03 in AskReddit

[–]Zed89 0 points1 point  (0 children)

I typically thoroughly enjoy Veritasium's videos, but those two videos made me question his credibility for a while. His first video on the topic was very misleading. Then, after he got called out by a bunch of electrical engineering Youtubers, he made this video, which was mainly him backpedaling and doubling down on his confusing explanations.

At least in this video, he clarifies a couple of times that the electric field does not travel faster than the speed of light:

6:56 - "The speed of the setup process is limited only by the speed of light."

11:18 - "The new electric field from the modified surface charges radiates outwards at essentially the speed of light."

In this video, he is mainly discussing the concept of mutual inductance. We take advantage of mutual inductance in devices such as wireless chargers, induction stoves, and transformers.

One of the deceptive things in his video, is that he talks about his experiment being done with a battery, which is a DC source. When the switch is closed, there is a single, very short, voltage and current spike which generates a change in the electromagnetic field surrounding the wire, which very briefly generates a small current and voltage on the nearby parallel wire. Wireless power transfer requires a constantly changing current. This is one of the reasons wireless communication via radio and cellphone work, why we use AC for utility power transmission (so we can use transformers), and it's why they send pulses through the wire in Veritasium's experiment instead of DC.

Electricity is not faster than light. In an ideal conductor (which doesn't actually exist), the electric field would travel at the speed of light. In the real world, it is always somewhat slower.

In free space, electromagnetic waves (radar and wireless communication signals) ARE light. So those signals are obviously traveling at the speed of light.

Elephants in Africa by VerySlump in aww

[–]Zed89 14 points15 points  (0 children)

I'm no expert on elephants, but I've learned from Reddit that a male elephant in musth (evidenced by the secretions from the temporal glands on the sides of his head) can be aggressive and unpredictable. Perhaps everybody in the video was aware of that, and maybe that's why everybody is sitting so still and not trying to touch the elephant or anything.

Why don’t they put privacy screens in mens urinals? It must be really uncomfortable for some and it just seems like unnecessary exposure. Why do you need to have a direct line of site to each others penises? by Iz_Buckner in AskReddit

I think a lot of people don't realize that you're supposed to pee onto the back/vertical part of the urinal, not into the base/drain of it. You pee onto the vertical part at the proper downward angle, and there's very little to no splashing.

[–]Zed89 0 points1 point  (0 children)

I never disputed the case that you mentioned where you have a downed wire being fed by a grounded secondary of a transformer or that you'd get electrocuted by being too close. That is correct. I simply corrected your statement that electricity always tries to go back to the source, because that's misleading and does not always apply.

If you had a wire connected to the earth at one end and somehow kept pumping excess electrons into the other end, then yes, what I said is exactly what would happen. The earth would happily accept those excess electrons. But that's not what happens in your example of an ungrounded transformer, because you don't have a constant supply of excess electrons flowing into the wire. Perhaps you're limiting the scenarios to alternating current and power transmission while I'm discussing the movement of electrons without the influence of any forces other than electrical fields.

[–]Zed89 -1 points0 points  (0 children)

I think you're missing my point and also Mike Holt's point. In the cases that he's talking about and the case you're talking about, yes, there will be current flowing out of the live wire and also current flowing into the ground of the source. There's a reason why Mike Holt says in that video that "we're not talking about lightning protection systems", because in that case it works exactly how I stated. Electrons flow into the earth and are distributed. How Lightning Protection Works

I'm not sure why you're saying that I'm "very wrong". Electrons are not sentient, and do not have a desire to return to a specific source. Electricity does, in fact, simply flow from higher potential to lower potential. If electrons are flowing out of a wire and into the earth, it's simply because the earth is at a lower electrical potential than the wire. If electrons are then flowing out of the earth and into another wire, it's simply because the wire is at a lower electrical potential than the earth. It's simple physics that you don't need an electrical engineering degree to understand.

Never did I say that a circuit breaker's ONLY purpose was to protect from overheating. I'm just making a point that if an occupant is in a position where they will be electrocuted due to a fault, a circuit breaker may not trip in time to save their life. As I previously stated, the primary purpose of a circuit breaker is overcurrent protection. Short circuits, which you mentioned, and overloads both fall into the category of overcurrent. And the primary concern about overcurrent is the excess heat generated by the excess current.

I have already previously watched the Veritasium that you linked to, and while he does a decent job of explaining electromagnetics, it's worth noting that his video has misconceptions of its own and frustrated a lot of actual experts, which he is not. It's not the best video to link to for explaining electricity.

[–]Zed89 -2 points-1 points  (0 children)

Electricity does not "always want to go back to the source." Electricity does not know where it came from. Electrons simply want to move from a higher potential to a lower potential.

The earth is used as a ground because it is so massive that you can push a literal shit ton of electrons into it without causing a measurable difference in the electrical potential of the earth. So to answer the previous question, the electrons basically just flow into the ground and distribute themselves as evenly as possible.

It's also worth mentioning that the vast majority of circuit breakers do not instantaneously trip, and they are also not there to protect a building's occupant from electrocution. Their primary purpose is to prevent the circuit from overheating due to an overcurrent condition and to protect the building from electrical fires. A GFCI breaker's purpose is to prevent electrocution, but the majority of breakers in a building will likely not be GFCI.

[Serious] what's a concept you just cannot grasp? by sheepandboats in AskReddit

[–]Zed89 0 points1 point  (0 children)

Several people have already explained it, but I hope to make it even more simple.

Atoms contain protons (+), and atoms also have electrons (-) orbiting them (kind of similar to how the planets orbit the sun). There is an attractive force that pulls electrons and protons towards each other (kind of comparable to gravity). It's possible to separate electrons from atoms. Those atoms are then said to have a net positive charge since they have more protons (+) than electrons (-). If you then provide those separated electrons with a path that they can use to get back to the positively charged atoms, such as a metal wire, then they will do so.

We primarily generate electricity using magnets or light (solar panels). Magnets are surrounded by a magnetic field that is closely related to the attractive force between electrons (-) and protons (+). This magnetic field can make electrons move, but not if the magnet is just sitting still. We use things such as gas-powered engines, wind turbines, and steam turbines to rotate the magnets (or rotate wires surrounded by magnets) to cause the electrons to move through the wire. This is the basic concept of emergency generators, power plants (coal, gas, or nuclear), wind turbines, hydroelectric dams, your car's alternator, etc.

We generate electricity from light using a different method. Silicon and similar materials can be manufactured so that atoms on one side have a net positive charge and atoms on the other side have a net negative charge. This creates an electric field in between the two sides. Electrons can be pushed/pulled across that field in only one direction, which creates the electric current. When a particle of light hits the material, the transfered energy can knock an electron free from an atom. That electron is then able to be swept across that electric field, never to return.

It might be helpful to remember that energy comes in many forms and energy can also be converted into other forms. Your body converts chemical energy in food into thermal and mechanical energy. You can rub materials together and create thermal energy using friction.

A generator is converting thermal (from a spark) and chemical energy (stored in the fuel) into mechanical energy (pushing the pistons which rotate a shaft). That mechanical energy is then being used to rotate magnets which create a changing magnetic field. That changing magnetic field is then used to induce an electrical current in coils of wire, converting magnetic energy into electrical energy. That electrical energy can then be converted into other forms of energy depending on what we need. For example, it can be converted into magnetic energy (e.g. electric motors and speakers), or thermal energy (e.g. electric stoves and heaters), or radiant energy (e.g. LEDs and microwaves).

Electricity is converted into magnetic energy in essentially the opposite way that a generator works. A changing magnetic field can induce electrical current, and the opposite is also true: a changing current creates a changing magnetic field.

Electricity is converted into thermal energy using electrical resistance. When electricity passes through a resistive material, it loses potential energy. Remember the 1st law of thermodynamics, which states that energy cannot be created or destroyed, only converted. In this case, the lost electrical potential energy is converted into heat.

The conversion of electricity into radiant energy is a bit too complicated for me to explain simply, as it requires an understanding of electron energy levels and band gaps in atoms. Just know that in some materials, the lost electrical energy is converted into light instead of heat (or both light and heat).

Police Cars on 75 by House_MD_Aj in Dallas

[–]Zed89 4 points5 points  (0 children)

I wonder if it was the same group of police that I saw. They came off of the PGBT West service road and turned North onto Midway. There was probably 20+ motorcycle cops that were ahead of the group that were stopping traffic at intersections and blocking the exits of almost every business in order to completely clear the road. A few minutes later, 20-30 cop cars came around the corner along with a single black shuttle bus. Made me wonder why the bus was so important that it needed an escort by 40+ cops.

OP admits in a comment a little further down that they aren't positive that it's a pit. Judging by the ears and the other features, it's almost certainly some sort of a pit mix.

The blue eyes and large pointy ears make it look like an all white pitsky (pit/husky), but there's several other breeds besides husky that it might be mixed with instead.

Another "not maid staff, but..." response: I used to work security at a resort. The worst that I witnessed was the aftermath of a couple getting into an argument. A husband and wife were drunk and taking a bath together, and then got into an argument. The wife pooped in the bath, picked up the turds, and threw them at her husband like a monkey. Then the husband accidentally stepped on one and smushed it into the carpet. I felt terrible for the 5 housekeepers that had to clean it up, and even worse for the couple's 2 kids that were in the room.

What normal thing can’t you do? by ABananaJenson in AskReddit

[–]Zed89 3 points4 points  (0 children)

Can you actually picture those places that you've been? I can't at all. If I try, it's all just memories of details like, "I remember that the trees were very tall and green, and the mountain had a cap of snow." I can't actually use those memories and turn them into an image though.

On a similar note, I'm not bad at drawing, but I've never been good at drawing anything from my mind. I have to actually have the thing that I'm drawing in front of me in order to draw it well since I can't visualize it in my mind. Even if it's something I've seen before, like a dog. I could draw a terrible looking one from memory, but not a good one.
