- 1If the frequency of the source is increased, the impedance of the circuit first decreases and then increases.✓
- 2If the net reactance of the circuit becomes equal to its resistance, then the current leads the voltage by 45°.
- 3At resonance, the voltage drop across the inductor is more than that across the capacitor.
- 4At resonance, the voltage drop across the capacitor is more than that across the inductor.
Correct answer
If the frequency of the source is increased, the impedance of the circuit first decreases and then increases.
