(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 (A), (C) and (D) only
- B (A), (D) and (E) only
- C (A), (B), (C) and (D) only
- D (A), (C) and (E) only
Answer & Solution
Correct Answer
(D) (A), (C) and (E) only
Step-by-step Solution
Detailed explanation
(A) Connection: In forward bias, the p-side is connected to the positive terminal and the n-side is connected to the negative terminal. This pushes majority carriers toward the junction. This statement is correct. (C) Voltage Direction: The built-in potential (barrier potential)…
