Where is the position of black wire in electric socket?
In a household circuit, with a "hot" conductor insulated black and a white neutral, the black wire should connect to the center terminal of the socket. The outside part of the socket usually has a brass screw (for the black wire) and a nickel screw (for the white wire).
What wire is hot on the cord going to the lamp socket?
The hot wire's cover is smooth and connected to what I call the "button" at the bottom of the socket. The neutral wire's cover has ridges and is connected to the screw shell of the socket.
How do you wire a wall plug socket?
Wall receptacles are wired in parallel. black to black, white to white, ground to ground.
What is an electric circuit with components pleased one after the other?
It is a series circuit, where all the lamps (for instance) is on the same wire. If one lamp fails, the rest lamps will also go out.
Why does a live wire shock the ground or trip the power when it comes in contact with the ground we walk on?
Because that completes a circuit. The live wire is one terminal of a high voltage transformer at the substation. The other terminal is grounded to earth ground, and earth is conductive.
