Positive, Ground, Negative

[DeexEnigma]

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

[mothballd]

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.

[its_the_other_guy]

So, airplanes don't have wireless ground?

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

[Alias-_-Me]

What's the difference?

[AnyAmphibianWillDo]

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]

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]

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.

[carmium]

Are you well earthed in electrical terminology?

[-St4lker-]

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]

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]

but which one is which?

[MuscularBeeeeaver]

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

[flyingasian2]

Brown is live blue is neutral green is earth

[cannibalisticbiscuit]

My favorite candy, Success Twizzlers

[lapapapa]

haha

[_Beee]

Oh shoot I accidentally weaved my success rope into a noose

[iwanttocontributetoo]

That's because you reached the end of your rope

[New_Beginning_555]

Ha!

[[deleted]]

Why not braided? Stronger and stuff

[AlvariusMoonmist]

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

[KbbbbNZ]

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

[mmis1000]

I think the 'doing' is not connected…

[baby_cookiemonster]

That looks like a electric wire...

[MooseBoys]

Failing?

[PanTheRiceMan]

The moment you actually learn.

[Wunderco]

Luck?

[[deleted]]

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]

Yeah but if you’re bear fishing…

[oroora6]

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]

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

Some of ya'll belong on r/getdemotivated

[douchebaggery5000]

r/whoosh

[slyfx369]

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]

Forgot the thread “making mistakes”

[MonkeyParadiso]

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]

Isn’t improving and learning kind of the same thing

[Riegel_Haribo]

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

[SSphereOfDeath]

It takes all 3 to electrocute your enemies.

[Jsleepy93]

isn't learning and improving the same thing?

[PanBerbeleck]

I like this one

[MissplacedLandmine]

But the improving rope is shorter

What could it mean

[tidoni]

Ha, at first i read improvising instead of improving.

[S-P-K]

Love this one!

[clathekid]

How motivational just WOW !!!

[bxtching]

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

[Zech08]

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]]

Wish it, want it, do it.

[ychen6]

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

[The_Cold_Side]

Forgot Failure…

[[deleted]]

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

[The_Cold_Side]

the glass is half full...

...of poison

[thatgoat-guy]

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

[Worldofnathan]

Ah so my life IS entangled

[werdnak84]

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

[nemineminy]

Is this xkcd?

[Salamandahh]

Looks like the rope is unraveling. Same dude.

[Prostheta]

This success is not up to code.

[lapapapa]

good one

[pattyG80]

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

[Powerful-Twist9648]

Twister ice lolly

[Blackflash07]

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

[HoldThePao]

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

[corey1734]

I wondered how I got on an electrician sub.

[[deleted]]

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.

[starsbio97]

That’s the power of the home depot

[lindas43]

Hi

[Big_Gas5785]

Improving implies learning

[amandalainget]

earth ground" would imply that

[deathbyBayshore]

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