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 :
Pick an option to check your answer.
Answer & Solution
Correct Answer
(C) Both Statement \(I\) and Statement \(II\) are true
Step-by-step Solution
Detailed explanation
Power will be maximum when impedance is minimum
\(Z =\left[ R ^2+\left( X _{ L }- X _{ C }\right)^2\right]^{\frac{1}{2}}\)
At resonance, \(X _{ L }= X _{ C }\)
\(Z_{\min }=R\)
