What is the peak-to-peak voltage of a sine wave with an RMS voltage of 120 volts?
84.8 volts
169.7 volts
240.0 volts
339.4 volts✓Bonne réponse
Explication
Peak voltage is 120 × 1.414 = 169.7 volts, and peak-to-peak is twice that, 339.4 volts. The 169.7 distractor is the peak value, which counts only one half of the waveform swing.
