Different voltages are applied across a ...

Different voltages are applied across a `P-N` junction and the currents are measured for each value. Which of the following graphs is obtained between voltage and current?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
`PN` junction has low resistance in one direction potential difference `+V`, so a large current flows (forwards biasing). It has a high resistance in the opposite potential difference direction `-V`, so a very small current flows (Revese biasing).
