Question

A resistor, 100 Ohm, is connected to an a.c. source given as v = 300 sin(wt). If w = 1256 rad/s, find the power dissipated by the resistor.
Options
A 900 W
B 700 W
C 450 W
Correct Answer
D 300 W
Correct Answer

Option C is the correct answer.

Detailed Explanation

Vrms2=90000/2=45000. P=Vrms2/R=450W.

Hint

Vrms2=90000/2=45000.
