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:

1. Statement I is false but Statement II is true
2. Both Statement I and Statement II are true
3. Statement I is true but Statement II is false
4. Both Statement I and Statement II are false

Correct answer: Both Statement I and Statement II are true

Solution

Both statements are accurate because resonance in an RLC circuit maximizes power transfer due to the impedance being minimized, while in a purely resistive circuit, the phase difference is zero, allowing for maximum power dissipation.
