Complete the following statement with the best suited option.

When a potential difference is applied across, the current passing through :

Options:

a pn diode at 300 K is finite, if it is reverse biased

an insulator at 0 K is zero

a semiconductor at 0 K is zero

a metal at 0 K is finite.

Correct Answer:

an insulator at 0 K is zero

Explanation:

At 0K, the insulator is purely non-conducting.
