In an $LCR$ resonant circuit,the phase difference between the current and the voltage is:

An $LCR$ circuit contains $R = 50 \, \Omega$,$L = 1 \, \text{mH}$,and $C = 0.1 \, \mu\text{F}$. The impedance of the circuit will be minimum for a frequency of:

The plot given below shows the average power delivered to an $LRC$ circuit versus frequency. The quality factor of the circuit is

What is resonance in an $LCR$ series circuit?

An $LCR$ circuit as shown in the figure is connected to a voltage source $V_{ac}$ whose frequency can be varied. The frequency,at which the voltage across the resistor is maximum,is......$Hz$.

In an $LCR$ series $AC$ circuit at resonance,the value of the power factor will be . . . . . . .
