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.

Answer» Correct Answer - 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).
