Measure of sharpness in an ac circuit is given by

In a series RCL circuit at resonance the applied ac voltage is 220 V. The potential drop across the inductance is 110V, what is the potential drop across the capacitor?​

Acceptor circuit is

An ac circuit contains a resistance R, capacitance C and inductance L in series with a source of emf ε = ε₀sin (ωt – Ø). The current through the circuit is maximum when:​
