An a.c. source is applied to a series LR circuit with $\text{X}_{\text{L}} = 3\text{R}$ and power factor is $\text{X}_1$. Now a capacitor with $\text{X}_{\text{c}} = \text{R}$ is added in series to LR circuit and the power factor is $\text{X}_2$. The ratio $\text{X}_1$ to $\text{X}_2$ is
In an $L - R$ circuit, the inductive reactance is equal to $\sqrt{3}$ times the resistance '$R$' of the circuit. An e.m.f. $\text{E} = \text{E}_0 \sin(\omega t)$ is applied to the circuit. The power consumed in the circuit is
A coil of resistance $450\Omega$ and self-inductance $1.5 \text{ henry}$ is connected to an a.c. source of frequency $\frac{150}{\pi} \text{ Hz}$. The phase difference between voltage and current is
A resistance of $200\Omega$ and an inductor of $\frac{1}{2\pi}\text{ H}$ are connected in series to a.c. voltage of $40\text{ V}$ and $100\text{ Hz}$ frequency. The phase angle between the voltage and current is

When alternating current is passed through an \( L-R \) series circuit, the power factor is \( \frac{\sqrt{3}}{2} \) and \( R = 50\Omega \), then the value of \( L \) is: 
 
\[ \left[ \cos \frac{\pi}{6} = \frac{\sqrt{3}}{2}, \quad \sin \frac{\pi}{6} = \frac{1}{2}, \quad \tan \frac{\pi}{6} = \frac{1}{\sqrt{3}} \right] \]
