-a-The rms value of current is Irms-VrmsR-220V100-x3A9-2-2A-b- -Net power is given by-xA0-P-V2R-2202100-484W

A 100 $Ω$ resistor is connected to a 220 V, 50 Hz ac supply.(a) What is the rms value of current in the circuit?
(b) What is the net
power consumed over a full cycle?

(a)
The rms value of current is $I_{r m s} = \frac{V_{r m s}}{R} = \frac{220 V}{100 Ω} = 2.2 A$

(b)

Net power is given by
$P = \frac{V^{2}}{R} = \frac{220^{2}}{100} = 484 W$
