How to Calculate the Current Through an Inductor

WebAn electrical field is generated when a current passes through the coil i.e. the inductor. Thus an electric field has been “induced”. The induced field is directly proportional to the length of the coil or the number of turns in … WebBasic Electronics - Inductance. The property of an inductor to get the voltage induced by the change of current flow, is defined as Inductance. Inductance is the ratio of voltage to the rate of change of current. The rate of change of current produces change in the magnetic field, which induces an EMF in opposite direction to the voltage source.
