What is the peak voltage of a 277 V RMS AC voltage?
A) 391.68 V
B) 434.85 V
C) 576.45 V
D) 695.90 V
RMS
Root Mean Square, a statistical measure of the magnitude of a varying quantity, commonly used to calculate the effective value of an alternating current.
Peak
The highest point or maximum value in a cycle, often used in the context of waves or signals.
V
Typically represents voltage in electrical contexts, indicating the electrical potential difference between two points.
- Determine and differentiate the peak, root mean square, peak-to-peak, and average magnitudes in AC circuits.

Final Answer :
A
Explanation :
The peak voltage (V_peak) of an AC voltage can be calculated from the RMS voltage (V_RMS) using the formula V_peak = V_RMS * sqrt(2). For a 277 V RMS AC voltage, the peak voltage is 277 * sqrt(2) = 391.68 V.
