Discovery of Electron

Discovery of Electron Sir J.J.Thomson and W.Crooks did many experiments with discharge tube for the discovery of electron. Discharge tube have tube like shape made from glass with two electrodes (Cathode -ve and Anode +ve) in vacuum created by vacuum pump connected to discharge tube. High electric potential is applied between two electrodes.   Discharge …
