Question

In p-n junction diode ______.

Options

• the current in the reverse biased condition is generally very small.

• the current in the reverse biased condition is small but the forward biased current is independent of bias voltage.

• the reverse bias current is strongly dependent on the reverse bias voltage.

• the forward bias current is very small in comparison to the reverse bias current.

Answer 1

In p-n junction diode the current in the reverse biased condition is generally very small.

Explanation:

In a p-n junction diode, under reverse bias, only a very small current flows due to minority carriers, called reverse saturation current. This current is almost independent of reverse voltage (until breakdown). In contrast, forward bias current increases rapidly with voltage.
