In an $L-C-R$ series $AC$ circuit,$L = 9 \ H$,$R = 10 \ \Omega$,and $C = 100 \ \mu F$. The $Q$-factor of the circuit is . . . . . . .

$A$ resistor of $R=6 \Omega$,an inductor of $L=1 \text{ H}$,and a capacitor of $C=17.36 \mu \text{F}$ are connected in series with an $AC$ source. Find the $Q$ factor.

An ideal resistance $R$,ideal inductance $L$,ideal capacitance $C$,and $AC$ voltmeters $V_{1}, V_{2}, V_{3}$ and $V_{4}$ are connected to an $AC$ source as shown in the figure. At resonance,

In a series $LCR$ resonant circuit,the capacitance is changed from $C$ to $3C$. To obtain the same resonant frequency,the inductance should be changed from $L$ to

In an $LCR$ series circuit,$C = 2 \mu F$,$L = 1 \ mH$,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?

Out of the following graphs,which graph shows the correct relation (graphical representation) for an $LC$ parallel resonant circuit?
