Yes. The electric current in a wire can be thought of as the movement of electrons, and all types of atoms have both positive and negative charges on their surfaces. When there is an excess of negative charge, it will flow to the other side to balance things out. A wire can carry a current and still be neutral because the electric charge is balanced. This means that there are equal amounts of positive or negative charges on both sides of an object, which makes it to not have any overall net electric charge at all.

Which one could you use for household appliances?

(a) A transmission line: this type of power cable transmits electricity from high voltage stations to end-users (b) An extension cord: these protective cables extend existing electrical outlets by connecting them together with additional sockets in between (c) A generator: these machines produce an alternating current through magnets rotating around coils when they pass over each other in an opposite pattern; usually powered by gasoline or diesel fuel
