Question
If the phase difference between Alternating Voltage and Alternating Current is $\frac{\pi}{6}$ and the resistance in the circuit is $\sqrt{300}\Omega,$ then the impedance of the circuit will be.
✓
Answer
- $20\Omega$
$\text{impedance}×\cos\theta = \text{resistance}$
$\text{impedance} = \frac{\text{resistance}}{\cos\theta}$
$=\frac{\sqrt{300}}{\frac{\cos\pi}{6}}$
$20\Omega$
