Alternating Current and Voltage - Engineering

Q1:

If the peak of a sine wave is 13 V, the peak-to-peak value is

A 6.5 V

B 13 V

C 26 V

D none of the above

ANS:C - 26 V

Peak-to-peak (pk-pk) is the difference between the maximum positive and the maximum negative amplitudes of a waveform, as shown below. If there is no direct current (DC) component in an alternating current (AC) wave, then the pk-pk amplitude is twice the peak amplitude.
