Total: 54

An L-C-R series circuit with 100Ω resistance is connected to an ac source. When only the capacitance is removed, the current lags behind voltage by ‌

.
When only the inductance is removed, the current leads voltage by ‌

. Then

Inductive reactance is 100Ω
Capacitive reactance is 100Ω
Impedance of L-C-R circuit is 100Ω
Maximum potential difference across inductor is equal to maximum potential difference across capacitor when all are connected in circuit.
