Q. Illustrate Inductance with example?

An ideal inductor is also an energy-storage circuit element (with no loss associated with it) like a capacitor, but representing the magnetic-field effect. The inductance in henrys (H) is defined by

where λ is the magnetic-flux linkage in weber-turns (Wb·t), N is the number of turns of the coil, and Nψ is the magnetic flux in webers (Wb) produced by the current i in amperes (A). Figure (a) illustrates a single inductive coil or an inductor of N turns carrying a current i that is linked by its own flux.

The general circuit symbol for an inductor is shown in Figure (b).According to Faraday's law of induction, one can write
