Inductor and Capacitor

As Electrical Engineers we know that Resistors, Inductors and Capacitors form the most important components in the entire field of study. I will try to explain some basic concepts of inductors and Capacitors here.

Inductors

1. Inductor is an element that stores energy in the form of magnetic energy.
2. An inductor does not allow sudden change of current.
3. The property of an inductor by which it opposes sudden change in current is called inductance.
4. The unit of inductance is Henry.
5. An inductor behaves as short circuit when supply is DC source.
6. The current through an inductor lags the voltage across the inductor,by 90 degrees in case of pure inductor.

Capacitors

1. Capacitor is an element that stores energy in the form of electrostatic energy.
2. An capacitor does not allow sudden change in voltage.
3. The property of a capacitor by which it opposes sudden change in voltage is called capacitance.
4. The unit of capacitance is Farad.
5. A capacitor behaves as open circuit when supply is DC source.
6. The current through a  capacitor leads the voltage across the capacitor,by 90 degrees in case of pure capacitor.
