alternating current Questions

The peak voltage of the AC source is equal to:

A series LCR circuit with inductance $10\text{H}$, capacitance $10\mu \text{F}$, resistance $50\Omega$ is connected to an ac source of voltage, $V=200\sin (100t)\text{volt}$. If the resonant frequency of the LCR circuit is ${\nu }_0$ and the frequency of the ac source is $\nu$, then:
