The Total solution for NCERT class 6-12
A 100 Ω resistor is connected toa 220 V, 50 Hz ac supply.
(a) What is the rms value of current in thecircuit?
(b) What is the net power consumedover a full cycle?
Resistance of the resistor, R = 100 Ω
Supplyvoltage, V = 220 V
Frequency, ν = 50Hz
(a) The rms value of current in the circuitis given as:
(b) The netpower consumed over a full cycle is given as:
P = VI
=220 × 2.2 = 484 W
