In a series LCR circuit, the voltage across an inductor, a capacitor and a resistor are 20 V, 20 V and 40 V, respectively, What is the phase difference between the applied voltage and the current in the circuit?

In a series LCR circuit, the voltages across the inductor (Vl = 20V) and capacitor (V c = 20V) cancel each other, making the circuit effectively resistive. Therefore, the phase difference between the applied voltage and the current is zero.
