Energy Storage in Inductors | Algor Cards
The inductance ( ( L )) of an inductor, a measure of its ability to store energy in a magnetic field, is a fundamental property that determines how much opposition the inductor presents to changes in current, thus affecting the induced voltage. The current ( ( I )), representing the flow of electric charge, is another critical factor in ...
