P N junction has low resistance in one direction of potential difference +V, so a large current flows (forward biasing). It has a high resistance in the opposite potential difference direction -V, so a very small current flows (Reverse biasing).

Q. 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?

$PN$ junction has low resistance in one direction of potential difference $+ V$ , so a large current flows (forward biasing). It has a high resistance in the opposite potential difference direction $- V$ , so a very small current flows (Reverse biasing).

PN junction has low resistance in one direction of potential difference +V, so a large current flows (forward biasing). It has a high resistance in the opposite potential difference direction −V, so a very small current flows (Reverse biasing).
