Yes, just at the main panel and not subpanels. The bonding of ground to neutral may be a screw or strap.
US NEC: The only place two circuits can share the same neutral (common) and ground wires is at the distribution panel, and that is only because those two conductors are tied together at the distribution panel.
The ground wires are twisted together and then connected to the GFCI ground. The black and white wires may also be twisted together and then using a jumper wire connected to the GFCI. Hard to say without seeing exactly how it is wired.
Only in the main electric panel.
The new cooktop has a 4 wire connection. Red & Black are hot. White is neutral, and green is ground. You existing panel is wired with 3 wires. Black & Red are hot and green is ground. There is no neutral wire. Connect the black to black, red to red, and then connect the white and ground together at the plug.
black wire is hot wire .And the white is the common or white is ground. Depends on what your talking about in an outlet or car battery. In a outlet the ground wire is green or bare copper. neutral is red and hot is black (I remember it by hot can kill you so black is death) if I am not mistaken. As for a car battery i think it's the opposite red is hot and black is neutral.

If you mean 2 bare copper wires those are the ground wires. Tie them together and then connect the light fixture ground wire which will be green or bare copper to those ground wires.

here is a diagram

If it is in a house generally black wires are hot and white wires are neutral (common). The neutral and ground wires are tied together in the main panel. With that said if you put 1 lead of your meter (set on AC voltage) on a black wire and the other lead to ground and you get 120 vac that wire is hot. If you get no reading it could be classified as common. This is the normal wiring practice. This is a basic assumption without having 1st hand knowledge of the wiring system If in doubt contact a qualified electrician
It is a plural noun when in sentences like this: There were ten wires on the ground. Wire is a common noun, but also a verb. It is a verb when in sentences like this. The electrician had to wire houses regularly. Wires can be used as a verb in: The electrician wires houses regularly.

Black/White/Ground power in and the same out. Tie the incoming and outgoing white wires together under a yellow wire nut and push them back in the box. Tie the ground wires together under a green wire nut and connect the pigtail from those ground wires to the ground screw on the switch. Connect the 2 black wires you have left to the 2 screws on the switch. Doesn't matter which black wire you connect to which screw.
where are the ground wires located where are the ground wires located where are the ground wires located
you just tap into the main wires with a wire tap that just clamps on then it will work
If speaker systems have Amplifier (home made).... Then you just combine their inputs so that ground couples with ground and signal input wires attached to the input wires or with connector.
