The value of alternating e.m.f. $(E)$ in the given circuit is (in $V$)

With an increase in the frequency of an $a.c.$ supply,the impedance of an $LCR$ series circuit:

In an $LCR$ circuit,the potential difference between the terminals of the inductor is $60\,V$,between the terminals of the capacitor is $30\,V$,and between the terminals of the resistor is $40\,V$. The supply voltage will be equal to ......$V$.

When a capacitor is connected in series with an $LR$ circuit, the alternating current flowing in the circuit:

Power dissipated in an $LCR$ series circuit connected to an $a.c.$ source of electromotive force (emf) $\varepsilon$ is:

When the $rms$ voltages $V_L, V_C$ and $V_R$ are measured respectively across the inductor $L$,the capacitor $C$ and the resistor $R$ in a series $LCR$ circuit connected to an $AC$ source,it is found that the ratio $V_L : V_C : V_R = 1 : 2 : 3$. If the $rms$ voltage of the $AC$ source is $100 \, V$,the $V_R$ is close to........$V$
