The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.

Generally, the atom has a neutral charge, but if it loses an electron, it becomes positively charged and if the atom gains an electron, it becomes negatively charged. Charged atoms are called ions.

The hindrance to the flow of electric charge is known as Resistance. The obstruction posed in the way of current carrying particles by fixed particles creates resistance in an electric circuit. Since ...

I hope that you are never in a situation in which you are in danger from a downed, but live, power line. However, if that ever happens, the recommended safety procedure is to move away with tiny, ...
