Static resistance of the diode

The resistance offered by the diode when connected in forward and reverse bias with a DC supply is known as the static resistance.

The static resistance of the diode is the ratio of diode voltage to diode current.

The static resistance is given by:

Dynamic resistance of the diode

The resistance offered by the diode when connected in forward and reverse bias with an AC supply is known as a dynamic resistance.

The dynamic resistance of the diode is the ratio of the change in diode voltage to the change in diode current.

The dynamic resistance is given by:
