When Reverse Bias Is Applied to a Diode It?

When a junction diode is Reverse Biased the thickness of the depletion region increases and the diode acts like an open circuit blocking any current flow, (only a very small leakage current will flow).

When a reverse bias is applied to a diode?

5.1.

Reverse bias usually refers to how a diode is used in a circuit. If a diode is reverse biased, the voltage at the cathode is higher than that at the anode. Therefore, no current will flow until the electric field is so high that the diode breaks down.

When a reverse bias is applied to a diode it will raise the potential?

Hence , In reverse biasing, the conduction across the p-n junction takes place due to minority carriers, therefore the size of depletion region (potential barrier) rises.
