When charges do not flow, the electricity is called _____.

Answer: Static electricity

Explanation: When charges do not flow, the electricity is called static electricity. Static electricity is an imbalance of electric charges within or on the surface of a material.  Materials are normally electrically neutral because they contain equal number of electrons and protons. When two materials are in contact, electrons may move from one object to another leaving an excess of positive charge on one material, and an excess of positive charge on another. When materials are separated they retain this charge imbalance.
