The peak voltage of the ac source is equal to:
the $rms$ value of the ac source
$\sqrt{2}$ times the $rms$ value of the $ac$ source
$\frac{1}{\sqrt{2}}$ times the $rms$ value of the $ac$ source
the value of voltage supplied to the circuit
The $AC$ voltage across a resistance can be measured using a
A series $LR$ circuit is connected to a voltage source with $V(t) = V_0\,\,sin\,\omega t$ . After very large time,current $I(t)$ behaves as $\left( {{t_0} > > \frac{L}{R}} \right)$
The root mean square value of the alternating current is equal to
When a $DC$ voltage of $200\, V$ is applied to a coil of self inductance $\frac{{2\sqrt 3 }}{\pi }\,H$, a current of $1\, A$ flows through it. But by replacing $DC$ source with $AC$ source of $200\, V$, the current in the coil is reduced to $0.5\, A$. Then, the frequency of $AC$ supply is......$Hz$
Which of the following components of a $LCR$ circuit, with $ac$ supply, dissipates energy
