for example‚ that rubbing a piece of amber with fur left an electric charge on its surface‚ which could then create sparks. For more about the history of the term electricity‚ see History of electricity. The electron as a unit of charge in electrochemistry was posited by G. Johnstone Stoney in 1874‚ who also coined the term electron in 1894. During the late 1890s a number of physicists posited that electricity could be conceived of as being made of discrete units‚ which were given a variety of

-Faraday- his major contributions were in the fields of electromagnetism and electrochemistry. He explained the basis of magnetic field through his studies on the effects of magnetic field around a conductor which carried Direct Current (DC). In 1831‚ Faraday made one of his most renowned discoveries‚ the principle of electromagnetic induction by using the "induction ring". The electricity was generated by means of electromagnetic effect. This was the first version of an electric transformer. He
