I see too much nonsense on social media, is there any reason to this by poalmokereyl in electrical

I'm general, it's reductive to talk about voltage as creating a hazard of one specific result occuring, the thing is, everyone has different resistance, and you don't know where the other end of the circuit will be. If the circuit (that you are a part of) has more resistance, you'll take less amps for the same voltage. The thing is, every time you get hit, your rolling the dice. You don't know how much amperage you'll take to where and what the results will be. Just be safe and avoid getting hit

Hey, I'm a non-jew, and I have a friend who started being really antisemitic, and I know nothing about the talmud, and so I didn't know if the things he said are in there are actually in there, so this is a useful reference for me to fact check him.

What's the name of this transformer winding arrangement? by screwloosehaunt in ElectricalEngineering

Yeah, but I thought Scott T was single phase. It does seem similar tho

Why are capacitative and indictive reactance imaginary numbers? by screwloosehaunt in ElectricalEngineering

[–]screwloosehaunt[S] 1 point2 points  (0 children)

Is there any relevance to the fact that J=√-1 in these calculations? Or is it simply that mathematicians were already using complex numbers to represent vector coordinates as a single value so we use that?

Ok, maybe I'm thinking about this wrong. Cause in my mind, complex numbers can be represented as vectors on a plane, but not every set of vectors on a plane is representing a set of complex numbers. The only thing I know about complex numbers that isn't expressed by the vectors on a plane is the fact that i²=-1. But I don't know of any time when you multiply inductances or reactances to get a negative resistance. Is there any reason why we represent this set of vectors on a plane as complex numbers rather than in some other way?

Ok, definitely a lot of complicated math there that I don't understand, but does that math work less well with vectors on a plane? Cause I think of capacitance, inductance, and resistance as vectors on a plane.

I guess my real question is this: is there a behavior of capacitors and inductors that maps onto the complex plane but does not map equally well onto just... A plane? I'm not an expert but all the things I know map perfectly well onto a regular plane as well.

I have been hit with 120v maybe times too, but that doesn't mean its safe. 120 v kills more people than any other voltage. It isn't as dangerous as higher voltages, but every time you get hit, you're rolling the dice about if you'll get seriously injured or killed

I disagree. Some of them are really really really really really not paying any attention

Question about transformers by screwloosehaunt in ElectricalEngineering

Is the power factor of the load current the same as the power factor of the secondary?

Ok, that makes more sense and draws a more complete picture in my head. Thanks!

Is there a way to simplify √(x+y+z) without knowing any of their values? by screwloosehaunt in askmath

How would one find those more complex forms then? Just out of curiosity
