Electron have an elementary charge of 1.60217662 × 10-19 coulombs. The electron is a subatomic particle, symbol e− or β−. 2.Electricity Electricity is the free flow of electrons. The presence of an electric charge, which can be either positive or negative, produces an electric field. On the other hand, the movement of electric charges, which is known as electric current, produces a magnetic field.
