Two statements are given below.
A. When the forward bias voltage across a p-n junction diode increases above a certain threshold voltage, the diode current increases significantly.
B. This current is called reverse saturation current.
Choose the correct answer from the options given below.

Asked in NEET 2026 · Biasing and I-V characteristics

Answer: (2) Statement A is true, but Statement B is false

Step-by-step solution

Idea: name the current by the bias that drives it.

Below the threshold the junction still carries most of the barrier, and the forward current is small.

Once the applied voltage passes that threshold the barrier is nearly cancelled and the current rises steeply, so A is a fair description.

Reverse saturation current is the small, nearly constant current that flows the other way under reverse bias, carried by minority carriers; it is measured in microamperes and has nothing to do with the steep forward rise.

So A is true and B is false.

Why the other options are wrong
