Electrons flow through a circuit from a power source and return to the power source via what?
a wire assumed to be at ground
What is the permissible neutral current?
I think you mean "what is the permissible imbalance between live and neutral current" All current supplied by the live wire should exit via the neutral. Any imbalance leaving via Earth is detected by an earth leakage circuit breaker . They trip at about 30 mA.
What is the function of a electric socket?
It allows you to disconnect the load without having to unplug the flexible cable.
What is the function of anti static mat?
An anti-static mat is usually made of a conductive plastic. Usually, on one corner there is a snap connector. From that snap connector there is a long, (usually GREEN) wire, as well as a coiled wire that goes to a wrist strap. The green wire goes to the round GROUND connector of an AC wall socket. The coiled wire that goes to a wrist strap goes just like that. Wrap the wrist strap around your wrist. The reason for this setup is, through the green wire to the ground connector, you put both the mat and your body at ground potential. It takes the static electricity from your body,via the wrist strap, and from the mat to ground. Be VERY CAREFULL!! YOU MUST KNOW WHERE THE GROUND IS ON AN AC OUTLET TO USE THIS AS I HAVE OUTLINED. If you do not know where the ground pin is on an AC outlet, you should not use it.
