Peak-to-peak value is equal to what multiple of the peak value?

Peak-to-peak value is equal to what multiple of the peak value?

• A. 2 x V_peak
• B. V_peak
• C. V_rms
• D. V_peak / 2

Answer: (A)

Peak-to-peak represents the total voltage swing from the highest positive value to the lowest negative value. For a sine wave centered at zero, the positive peak is V_peak and the negative peak is -V_peak. The difference between them is V_peak - (-V_peak) = 2 V_peak. So the peak-to-peak value is twice the peak value. For example, with V_peak = 5 V, V_pp = 10 V. This isn’t equal to V_rms, and it isn’t V_peak/2.
