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

Here,R = 100 Ω , ${ E }{ v }$ = 220 V, v = 50 Hz
(i)${ I }{ v }$ =
${ E }{ v }$ / R = 220/100 = 2.2 A
(ii) Net power consumed
${ P }{ av }$ =
${ E }_{ v }$Iv
= 220 x 2.2 = 484 W
