The word electricity was given by Sir Thomas brown in the year 1646. This electricity is produced on rubbing and hence it is also called frictional electricity. When this electricity is not allowed to flow, then it is called static electricity. Electric charge:- A body is Said to Possess electric charge if it either has an excess of electrons or it is deficient in electrons. There are two types of charges: positive charge
and negative charge. A body is charged by the transfer of electrons. If it gains electrons, it is negatively charged and if it loses electrons it is positively charged. Let's test yourself about Electricity Quiz Questions And Answers.
