A 150 ohms resistor, 20 uF capacitor, and 300 mH inductor are in a series circuit, connected to an AC source, with an amplitude of 40 V. The frequency of the power supply is set to 75% of the resonant frequency. Find the amplitude of the current and the phase angle between the current, and the voltage across power supply. Show your work and explain each step. Include a phasor diagram, showing the reactances, resistance, impedance, and phase angle.
