What is the new value of capacitance

Reference no: EM13250800

Consider a a series circuit containing an inductor (100 mH), a capacitor (40 microF) and a resistor (50 ohms). It is connected to the AC mains (f = 60 Hz, VRMS = 120 V)

a) What is the rms current in this circuit?

b) Draw a voltage phasor diagram for this situation

c) Does the voltage lead or lag the current? What is the phase angle between them?

d) What is the power dissipated in the circuit?

The capacitor is now adjusted so that the circuit is in resonance.

e) What is the new value of capacitance?

f) What is the phase angle between the voltage and current?
