Given below are two statements:
**Statement I:** Maximum power is dissipated in a circuit containing an inductor, a capacitor and a resistor connected in series with an AC source, when resonance occurs.
**Statement II:** Maximum power is dissipated in a circuit containing pure resistor due to zero phase difference between current and voltage.
In the light of the above statements, choose the correct answer from the options given below.
Answer: (B) Both Statement I and Statement II are true
At resonance $Z=R$, the current is maximum and $\cos\phi=1$, giving maximum power (I true). In a purely resistive circuit $\phi=0$ and $\cos\phi=1$, the largest possible power factor (II true).
