Electric current

Electric current is a flow of electric charge. Electric charge flows when there is voltage present across a conductor and can be measured using an ammeter. The SI unit for measuring an electric current is the ampere, which is the flow of electric charges through a surface at the rate of one coulomb per second.

Electric currents cause many effects, notably heating, but also induce magnetic fields, which are widely used for motors, inductors and generators.Read more
