Question

An alternating current is given by
Vi= Vm sin [ 159•2π]t. calculate maximum
voltage . frequency, time
period and instantaneous
voltage at 2.5M Sec​

Answer 1

Answer :

Resistance of the resistor, R = 100 Ω

Supply voltage, V = 220 V

Frequency,v= 50 Hz

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

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

P = VI

= 220 × 2.2 = 484 W
