The voltmeter in the circuit shown in the figure is ideal. The transformer has two identical windings with perfect coupling. The reading on the voltmeter will be
- A. 440 V
- B. 220 V
- C. 110 V
- D. Zero
Answer: D. Zero
Explanation: As the voltmeter is ideal and coupling is perfect, the voltage across secondary terminals will be the same as on the primary side (in terms of magnitude and phase, considering dot convention and identical windings). Hence, the potential difference across the voltmeter will be zero.
