(b) What is the net power consumed over a full cycle?

(a) What is the rms value of current in the circuit?

(b) What is the net power consumed over a full cycle?

Answer

Resistance of the resistor, *R *= 100 Ω

Supply voltage, *V* = 220 V

Frequency, *ν*** ****= **50 Hz

**(a)** The rms value of current in the circuit is given as:

I = V / R

= 220 / 100 = 2.20 A

**(b) **The net power consumed over a full cycle is given as:

*P* = *VI*

= 220 × 2.2 = 484 W
