Question

Power delivered by the source of the circuit becomes maximum, when
(a) ωL=ωC
(b) $\omega L=\frac{1}{\omega C}$
(c) $\omega L=- \bigg \lgroup \frac{1}{\omega C} \bigg \rgroup ^2$
(d) $\omega L = \sqrt{\omega c}$

Answer 1

answer : option (b)

explanation :- we know, power delivered by the source of the circuit becomes maximum when, load resistance equals to source resistance.

we know, in L-C-R circuit,

load resistance is inductive reactance and source resistance is reactance of capacitor.

e.g., $X_L=X_C$

or, $\omega L=\frac{1}{\omega C}$

hence, Power delivered by the source of the circuit becomes maximum, when $\omega L=\frac{1}{\omega C}$
