You're Grounded

While it is plugged into the wall.

Since ground is relative you can just call it whatever you want to get away from it.

"You're Grounded" I used to hear these words from my parents quite often when I was in high school. I wasn't until I got into electronics that I *really* understood what they meant......

Then again, if you completely remove the ground from any circuit, the circuit will not function. Thus getting grounded may just be a good thing...... At least once and a while :)

Now, how does one totally remove the ground from a circuit??????

It's like. How do you remove the sides from a square and still have a square?

If by ground meaning the return path then by the charge conservation law that electric charge cannot be created or destroyed you cannot remove the ground and still have a closed circuit.

The closest I can think of a groundless circuit(no obvious return path) is an eddy current where the circuit is in the conductor. Removing the ground in that case could result in removing everything. No ground no circuit.

Maybe firing charged particles into space might qualify as near groundless. Charge goes out but the return path (the ground) is a mystery path. The solar wind from the sun is a stream of charged particles. It's charged, it's moving, therefore there's a current so I suppose there's a circuit somewhere. It's an absolutely huge complicated circuit. So big that it could be approximated as groundless?

With a Glock 9mm?

You are an idiot. And that was before you went senile.

The next time someone tells you, "Accentuate the positive, eliminate the negative," ask them, "How the hell can I jump-start my car without a negative?" >:->

With a shovel?

Just call it a reference voltage, and you no longer have a ground.

I like that one :)

Pull up the damn ground rod.

Set it up on big insulators! I've been to some national labs where they have ion sources elevated to a couple hundred kV. So, it is a whole room sitting up on great big ceramic insulators, and there's a guy with a grounding cable with a hook on one end and a long handle on the other to ground the room before anyone goes in or out.

There is a video on youtube where a guy exits a helicopter and crawls on live 500,000 volt wires to inspect them. I think this is the URL.

Notice that the guy needs chain mail long johns to replace the (Faraday cage) room.

The 'inspection' takes place without being out on the wire. When they go out on the wire, it is for servicing. Usually the conductor bundle spacers, and insulator replacements. Full body shark suit required.

Nice work if you can get it :)
