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:
Text Solution
Verified by ExpertsB
The formula for impedance is given by
At resonance, X L = X c . So, Z min = R
Power will be maximum when impedance is minimum. Thus the maximum power occurs in a purely resistive circuit.
