A resistor and a capacitor are in series across a 20 V ac source. Circuit impedance is 4.33 kΩ. Current flow in the circuit is

4.6 mA

9.2 mA

92 mA

460 mA

Correct Answer : 4.6 mA

The power factor (PF) indicates how much of the apparent power is true power.

True

False

Correct Answer : True

The expression of voltage across resistor in the circuit shown below is?

V_R = 20(e^t)V

V_R = 20(e^-t)V

V_R = 20(-e^t)V

V_R = 20(e^-t)V

Correct Answer : V_R = 20(e^-t)V

Explaination : The expression of voltage across resistor in the circuit is V_R = iR =(2(e^-t))×10=20(e^-t)V.
