Question

Power delivered by the source of the circuit becomes maximum, when .

• A. $\omega L$=$\omega C$
• B. $\omega L$=-$\frac{1}{{\left(\omega C\right)}^2}$
• C. $\omega L$=$\sqrt{\omega C}$
• D. $\omega L$=$\frac{1}{\omega C}$

Answer 1

The correct option is D $\omega L$=$\frac{1}{\omega C}$

Power delivered is maximum when capicitive reactance and inductive reactance cancel out each other.
