Question
In a series LCR circuit, voltages across an inductor, a capacitor and a resistor are 30 V, 30 V and 60 V respectively. What is the phase difference between applied voltage and current in the circuit?
Solution
Given, a series LCR circuit.
Voltage across inductor, VL = 30 V
Voltage across capacitor, Vc = 30 V
Voltage across resistor, VR = 60 V
Voltage across inductor, VL = 30 V
Voltage across capacitor, Vc = 30 V
Voltage across resistor, VR = 60 V
since, VL= Vc = 30 V,
therefore,
i.e., there is no phase difference between applied voltage and current in the circuit.
