Question

How can solve lcr circuit question

Answer 1

An AC circuit is composed of a serial connection of:

a resistor with resistance 50 Ω,

a coil with inductance 0.3 H

and a capacitor with capacitance 15 μF.

The circuit is connected to an AC voltage source with amplitude 25 V and frequency 50 Hz. Determine the amplitude of electric current in the circuit and a phase difference between the voltage and the current.
