Diodes are most commonly used for rectification of alternating voltages. This is because, in diode

(A) current flows in one direction only
(B) forward bias resistance is low as compared to reverse bias resistance
(C) reverse current is independent of the voltage applied
(D) reverse current is linearly dependent on the voltage applied

Choose the correct answer from the options given below:

(A) and (B) only

The correct answer is Option (2) → (A) and (B) only

Diodes allow current to flow primarily in one direction (forward bias) and block it in the reverse direction.

Therefore, this property makes them suitable for converting alternating voltage to direct voltage (rectification).

Correct option: (A) current flows in one direction only.
