In the circuit shown L and C are in series. Therefore, it is a series resonance circuit Hence current through a.c. source is maximum

Q. In the circuit shown in figure, at resonance

the power factor is zero

the current through the a.c. source is minimum

the current through the a.c. source is maximum

currents through $L$ and $R$ are equal

In the circuit shown $L$ and $C$ are in series. Therefore, it is a series resonance circuit Hence current through $a . c$ . source is maximum
