The Electron Since electrical engineering generally deals with tiny particles called electrons, these small particles require detailed study. We know that an electron is a negatively charged particle having negligible mass. Some of the important properties of an electron are Charge on an electron, e = 1.602 x 10-19 coulomb Mass of an electron, m = 9.0 x 10-31 kg Radius of an electron,r = 1.9 x 10-15 metre The ratio elm of an electron is 1.77 x 10-11 coulombs/kg. This means that mass of an electron is very small as compared to its charge. It is due to this property of an electron that it is very mobile and is greatly influenced by electric or magnetic fields | |
