Read the following statements carefully:
(A) The average power in an inductor over one complete cycle is zero.
(B) Self-inductance plays the role of inertia.
(C) Mutual inductance of a pair of coils depends on their separation as well as their relative orientation.
(D) The capacitive reactance increases with increase in frequency of applied a. c.
Choose the correct answer from the options given below :
- A (A), (B) and (C) only
- B (A), (C) and (D) only
- C (B), (C) and (D) only
- D (A), (B), (C) and (D)
Answer & Solution
Correct Answer
(A) (A), (B) and (C) only
Step-by-step Solution
Detailed explanation
Statements (A), (B), and (C) are correct: Average power in a pure inductor is zero because energy alternates between source and magnetic field; inductance acts as electrical inertia; and mutual inductance varies with coil distance and angle. A) (A), (B) and (C) only.
