Choose the correct answer from the options given below :
- A (A), (B) and (D) only
- B (A), (B) and (C) only
- C (A), (B), (C) and (D)
- D (B), (C) and (D) only
Answer & Solution
Correct Answer
(B) (A), (B) and (C) only
Step-by-step Solution
Detailed explanation
Hysteresis Loss (1): Caused by the repeated reversal of magnetization in the core. Energy is lost as heat due to the magnetic friction of the core material. Flux Leakage (2): Occurs when not all magnetic lines of force from the primary coil pass through the secondary coil. This…
