Under forward-bias of a p-n diode

(A) p-side of the diode is connected to the positive terminal of the battery and n-side to the negative terminal
(B) p-side of the diode is connected to the negative terminal of the battery and n-side to the positive terminal
(C) The direction of the applied voltage (V) is opposite to the built-in potential drop
(D) The direction of the applied voltage (V) is the same as the built-in potential drop
(E) The magnitude of the diode forward current is usually in mA

Choose the correct answer from the options given below:

(A), (C) and (E) only

The correct answer is Option (4) → (A), (C) and (E) only

(A) Correct: In forward bias, the p-side is connected to the positive terminal and the n-side to the negative terminal.

(B) Incorrect: This corresponds to reverse bias.

(C) Correct: The applied voltage opposes the built-in potential barrier, reducing it and allowing current flow.

(D) Incorrect: The applied voltage is not in the same direction as the built-in potential.

(E) Correct: Forward current is usually in the order of mA.
