Document Summary

Just as with capacitors, inductors have transients with respect to time. The difference here is that the inductor is a current device rather than a voltage device. t di( ) t d i( )= v( ) t v( ) t t. Instantaneous power: p( ) t v( )i( ) t t. There are two types of inductance: self-inductance and mutual inductance. Mutual inductance is associated with inductive coupling between two or more inductors. The industry standard is to apply the term, inductance, to the term self-inductance. The symbol for inductance is l and the unit of inductance, h, is the henry. Inductor models charge which we normally think of as storing a voltage. The inductor stores energy in the form of magnetic flux which we normally think of as storing current. In its most basic form, a capacitor stores energy in the form of an electrical. Example: the following voltage waveform is applied to the inductor shown.
