Question

Assertion : During reverse biasing a diode doesn't conduct current. 

Reason : It narrows the depletion layer.

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

The correct option is (c).

Explanation:

During reverse biasing, the depletion layer widens, and so there is more resistance for an electron or a hole to cross that layer to conduct current.
