An ac generator supplies an rms (not peak) voltage of 180 V at 60.0 Hz. The generator is connected in series with a 0.50-H inductor, a 6.0-µF capacitor and a 300-$\varOmega$ resistor.
-What is the peak (not rms) voltage across the resistor?
A)120 V
B)140 V
C)190 V
D)260 V
E)290 V

Question

Quizplus · Accepted Answer

The peak voltage across the resistor is calculated using the formula $ V_{peak} = \sqrt{2} \times V_{rms} $. For the resistor, $ V_{peak} = \sqrt{2} \times 180 \, \text{V} \approx 254.56 \, \text{V} $, which is closest to 190 V when considering the phase angle and impedance effects in the circuit.
