A `100 Omega` 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?

Text Solution

Verified by Experts

Here, `R = 100 Omega, E_(v) = 220 V, v = 50 Hz`
(a) `I_(v) = ?, I_(v) = (E_(v))/(R ) = (220)/(100) = 2.2 A`
(b) Net power consumed over a full cycle, `P = E_(v) I_(v) = 220 xx 2.2 = 484 W`
