Question

The power dissipated by a 72 Ohm resistor connected to a sinusoidal AC source is 24 W. Determine the peak-to-peak voltage across the resistor.
Options
A 117.5 V
Correct Answer
B 58.8 V
C 41.5 V
D 235 V
Correct Answer

Option A is the correct answer.

Detailed Explanation

Vrms=sqrt(PR)=41.57V. V0=Vrms*sqrt2=58.79V. Vpp=2V0=117.5V.

Hint

Vrms=sqrt(PR)=41.57V.
