In a series $LCR$ circuit,the frequency of the source is half of the resonance frequency. The nature of the circuit will be:

$A$ circuit of negligible resistance has an inductor of $0.16 H$ and a capacitor of $25 \mu F$ connected in series with an alternating voltage source. The resonant frequency of the circuit is:

In a series $LCR$ circuit with $C = 2 \mu F$,$L = 1 \ mH$,and $R = 10 \ \Omega$,when the current in the circuit is maximum,what is the ratio of the energy stored in the capacitor to the energy stored in the inductor?

$L=2 \text{ H}, C=5 \text{ mF}$ and $R=12 \text{ } \Omega$ are connected in series to an a.c. generator of frequency $50 \text{ Hz}$. Then:

$A$ parallel combination of a pure inductor and a capacitor is connected across a source of alternating e.m.f. '$e$'. The currents flowing through the inductor and the capacitor are $i_{L}$ and $i_{C}$ respectively. In this parallel resonant circuit,the condition for the currents $i$,$i_{L}$,and $i_{C}$ is ($i =$ net r.m.s. current in the circuit).

In a series $L-C-R$ circuit,$C = 2 \mu F$,$L = 1 \ mH$,and $R = 10 \ \Omega$. What is the ratio of energies stored in the inductor and the capacitor when the maximum current flows in the circuit?
