Share:
- 1The capacitive reactance becomes twice the inductive reactance, and the current lags the voltage by 90°.
- 2The inductive reactance exceeds the capacitive reactance, and the power factor becomes zero.
- 3The inductive reactance equals the capacitive reactance, and the current is completely in phase with the applied voltage.✓
- 4The resistance of the circuit is minimized, causing the voltage to lead the current by 45°.
Correct answer
The inductive reactance equals the capacitive reactance, and the current is completely in phase with the applied voltage.
