aryajur said:Consider a passive LCR circuit, this circuit is a voltage divider at most frequencies but at the resonant frequency w=1/√(LC) the voltage across L or C would be an amplified voltage. So this is like a voltage divider at 1 frequency and a voltage amplifier at 1 particular frequency.
Consider the values of components:
R = 10Ω, L=1mH, C=1nF and Vac=100V
then calculate the voltage across the inductor in steady state at a freuqncy of 1 KHz and 1MHz you will see how that happens.
