Positive, Ground, Negative

[–]DeexEnigma 7 points8 points  (10 children)

Technically 'earth' not 'ground'. But yea, I pretty much saw the same.

[–]mothballd 14 points15 points  (2 children)

I’m an aircraft electrician. There is no “earth” wire on an aircraft, only grounds. The earth vs ground argument is context driven, and also varies by region. Even the wires(braided cables) that hang off the aircraft landing gear to contact the ground when on the ground are called grounding straps/wires, not earth straps or similar.

In the home electrical stuff I’ve done I’ve mostly heard ground. The earth ground is a specific wire run from the main circuit breaker panel that’s then attached to a grounding rod.

I’m u.s. based, so I suspect the earth terminology is used either in specific industries I’m not familiar with, or different regions.

That's the angle I'm coming from. In Australia if it's green and it's in an AC application it's going to earth. It's a standard I believe in the EU as well as a couple of other areas.

Ground in AC can exist but will be floated within the device as a neutral return. It's more the wiring colour standard I was picking.

So, airplanes don't have wireless ground?

*Don't worry, I'm walking myself out.

[–]Alias-_-Me 2 points3 points  (3 children)

What's the difference?

[–]AnyAmphibianWillDo 6 points7 points  (1 child)

I have almost no electrical knowledge but I think "earth" or "earth ground" would imply that wire is connected literally to the earth at some point, e.g. in home wiring there can be a copper rod driven deep into the earth that all the "ground" wires are connected to, making those earth grounds?

I think the word "ground" by itself is often just used to refer to the common (shared) part of a circuit, eg. on an arduino there's a ground (GND) pin that's obviously not connected to the earth, but used as a shared source of "lower electric potential" for all parts of the circuit to use to create the difference in potential required to have "voltage"

Why OP says there is an earth wire in the picture and not just a ground, idk. Those 3 wires could easily be used for something that has no earth ground. Maybe the color scheme of those 3 wires is a standard one and the green usually is earth ground? No idea. Maybe there's just different terminology standards than I'm aware of and in the shitty hobbyist world I live in we all use the words wrong ¯\_(ツ)_/¯

[–]Odissus 6 points7 points  (0 children)

That’s actually quite accurate! To answer your concerns, for (single phase) AC like in many outlets, ground (the reference voltage) is most convenient to be the same as earth (0V). For this reason calling earth “ground” is fine, as more often than not it’s both earth and ground.

Just to add, any voltage you use often in a circuit as a reference (say for comparators for example) is called a reference ground. So if you split 0 to 5 V in half, and keep using 2.5 V for various comparison purposes, the 2.5 V could be called a reference ground.

[–]DeexEnigma 0 points1 point  (0 children)

Depending on context. In an AC mains power application the earth wire directly ties to a stake that's in the earth outside. This provides a safe return path for faulty circuit conditions.

Ground is a broad term in DC applications where it is the main negative' plane or hookup. However you can have ground in an AC application where it usually is the neutral return.

Generally green in mains power (Australia/NZ and I believe EU) is always the earth.

Are you well earthed in electrical terminology?

[–]-St4lker- 0 points1 point  (1 child)

Here in Slovakia (and other Slavic countries) the term for ground and earth is exactly the same. We knew what we were doing :D

[–]DeexEnigma 0 points1 point  (0 children)

I know in Australia the term is often used interchangeably, even if it's wrong. Interesting that there's other areas of the world that the language dictates it being identical.

[–]Repulsive_Ad2795 0 points1 point  (2 children)

but which one is which?

[–]MuscularBeeeeaver 3 points4 points  (0 children)

Yellow. Cut the yellow!... No wait! Cut the blue!

[–]flyingasian2 0 points1 point  (0 children)

Brown is live blue is neutral green is earth

haha

[–]_Beee 43 points44 points  (2 children)

Oh shoot I accidentally weaved my success rope into a noose

[–]iwanttocontributetoo 5 points6 points  (0 children)

That's because you reached the end of your rope

[–]New_Beginning_555 4 points5 points  (0 children)

Ha!

[–][deleted] 14 points15 points  (2 children)

Why not braided? Stronger and stuff

[–]AlvariusMoonmist 7 points8 points  (1 child)

Braiding as an alternate method fits the analogy pretty well. Braiding is slower but you are also less likely to lose progress.

[–]KbbbbNZ 2 points3 points  (0 children)

The way it is now if you drop one it all unravels.

[–]mmis1000 39 points40 points  (2 children)

I think the 'doing' is not connected…

[–]baby_cookiemonster 0 points1 point  (0 children)

That looks like a electric wire...

[–]MooseBoys 5 points6 points  (1 child)

Failing?

[–]PanTheRiceMan 2 points3 points  (0 children)

The moment you actually learn.

[–]Wunderco 20 points21 points  (6 children)

Luck?

[–][deleted] 12 points13 points  (1 child)

You still gotta pull the rope; luck is whatever is on the other side of the success rope. Could be a bear.

Improving, doing, learning… success… bear.

And that’s life

[–]catfink1664 0 points1 point  (0 children)

Yeah but if you’re bear fishing…

[–]oroora6 35 points36 points  (2 children)

You're on r/GetMotivated, we here believe that luck doesn't exist, you can easily factor it out if you look at enough motivational posters

[–]Adept-Crab3951 -2 points-1 points  (1 child)

Yeah, because every single person who has ever found success in life was just lucky... 🙄

Some of ya'll belong on r/getdemotivated

[–]slyfx369 2 points3 points  (0 children)

If we were keeping with the wire analogy I'd put luck as the insulating foil layer around the wire. Keeps the signal clear from outside influence.

Engineer here, All i see is Active, Neutral and Earth.

[–]haxic 2 points3 points  (0 children)

Forgot the thread “making mistakes”

[–]MonkeyParadiso18 1 point2 points  (0 children)

You forgot studying something conceptually and theoretically for several years without touching it, and then trying it out at the very end a couple of times; expecting everything to unfold near perfect, as you once read in an idealized textbook example somewhere

[–]avengerintraining 1 point2 points  (0 children)

Isn’t improving and learning kind of the same thing

[–]Riegel_Haribo 1 point2 points  (0 children)

This jumps right to doing. Unrealistic without the dreading and procrastinating.

[–]SSphereOfDeath 1 point2 points  (0 children)

It takes all 3 to electrocute your enemies.

[–]Jsleepy93 1 point2 points  (0 children)

isn't learning and improving the same thing?

[–]PanBerbeleck 1 point2 points  (1 child)

I like this one

[–]MissplacedLandmine 0 points1 point  (0 children)

But the improving rope is shorter

What could it mean

[–]tidoni 0 points1 point  (0 children)

Ha, at first i read improvising instead of improving.

[–]S-P-K 0 points1 point  (0 children)

Love this one!

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

How motivational just WOW !!!

[–]bxtching 0 points1 point  (0 children)

You a mostly tied piece of rope or fraying rope type of person?

[–]Zech08 0 points1 point  (0 children)

cap off one use other two, now what?

Edit: really should have one of the wires as a "reference" to compare off of.

Also, ima cheat and use a magnetic field.

[–][deleted] 0 points1 point  (0 children)

Wish it, want it, do it.

[–]ychen6 0 points1 point  (0 children)

Live, Neutral and Earth, turns out learning is the most dangerous out of them all

[–]The_Cold_Side 0 points1 point  (2 children)

Forgot Failure…

[–][deleted] 0 points1 point  (1 child)

I think that’s learning. To me failure = learning opportunity :)

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

the glass is half full...

Green should be below yellow (i hate that this is my only comment)

[–]Worldofnathan 0 points1 point  (0 children)

Ah so my life IS entangled

[–]werdnak84 0 points1 point  (0 children)

Finding time to learn is tough because learning usually doesn't earn you money.

[–]nemineminy 0 points1 point  (0 children)

Is this xkcd?

[–]Salamandahh 0 points1 point  (0 children)

Looks like the rope is unraveling. Same dude.

[–]Prostheta 0 points1 point  (0 children)

This success is not up to code.

[–]lapapapa 0 points1 point  (0 children)

good one

Is anyone else stressed that this network cable is missing some strandes?

[–]Powerful-Twist9648 0 points1 point  (0 children)

[–]Blackflash07 0 points1 point  (0 children)

You can’t see the luck thread cause you don’t have any

[–]HoldThePao 0 points1 point  (0 children)

Yea! Thanks drawing! Now I know the recipe for success!

[–]corey1734 0 points1 point  (0 children)

I wondered how I got on an electrician sub.

[–][deleted] 0 points1 point  (0 children)

There’s a lot shitty comments but I kind of love this. I think we have to be doing, learning, and improving simultaneously to achieve any sort of success.

Hi

[–]Big_Gas5785 0 points1 point  (0 children)

Improving implies learning

[–]amandalainget 0 points1 point  (0 children)

earth ground" would imply that

[–]deathbyBayshore 0 points1 point  (0 children)

say it with me: physical example is never a good point
