### Alternating Current

goals
A source of constant voltage $V$ is connected to a resistance $R$ and two ideal inductors $L_{1}$ and $L_{2}$ through a switch $S$ as shown. There is no mutual inductance between the two inductors. The switch $S$ is initially open. At $t=0$, the switch is closed and current beings to flow. Which of the following options is/are correct?
Which of the following option is correct for an ideal capacitor connected to a sinusoidal voltage source over a complete cycle?
In the given figure, the current amplitude is :
The above figure shows a cross-over network in a loud speaker system. One branch consists of a capacitor $C$ and a resistor $R$ in series $($the tweeter$).$ This branch is in parallel with a second branch $($The woofer$)$ that consists of an. inductor $L$ and a resistor $R$ in series. The same source voltage with angular frequency $\omega ($from an amplifier$)$ is applied across each parallel branch.
The power factor in a circuit connected to an AC. The value of power factor is
