In an $LCR$ circuit,at resonance

In a series $LCR$ circuit, $C = 2 \text{ } \mu\text{F}$, $L = 1 \text{ mH}$, and $R = 10 \text{ } \Omega$. What is the ratio of energies stored in the capacitor and inductor when maximum current flows through the circuit (in $: 1$)?

The figure shows a series $LCR$ circuit connected to a variable frequency $230 \; V$ source. Given $L = 5.0 \; H$,$C = 80 \; \mu F$,and $R = 40 \; \Omega$.
$(a)$ Determine the source frequency which drives the circuit in resonance.
$(b)$ Obtain the impedance of the circuit and the amplitude of current at the resonating frequency.
$(c)$ Determine the $rms$ potential drops across the three elements of the circuit. Show that the potential drop across the $LC$ combination is zero at the resonating frequency.

What is the sharpness of resonance and obtain an equation for the $Q$ factor?

Assertion: In a series $LCR$ circuit,resonance can take place.
Reason: Resonance takes place if inductive and capacitive reactances are equal and opposite.

For a series $LCR$ circuit at resonance,the statement which is not true is:
