The flow of electrons is referred to as electricity. The imbalance between the electric charges in a body, specifically the imbalance between the negative and the positive charges on a body, is known as static electricity. The electrostatic generator can produce static electricity.
For example, when a comb is rubbed into hair and taken near small pieces of paper, the paper pieces get attracted to the comb.
