To be ultra pedantic, 120VAC refers to the root mean square (RMS) voltage of the sinusoidal waveform present in household electrical systems. The RMS value represents the effective voltage that produces the same amount of power as a DC voltage of the same value. In the case of a 120VAC circuit, the peak voltage, which represents the maximum value of the voltage waveform, is approximately 169.7 volts. This peak voltage is achieved when the voltage swings between +169.7V and -169.7V in a full sine wave pattern. |
