Peak-to-Peak Value The peak-to-peak value is measured from the maximum positive

value to the maximum negative value of a cycle. If the peak

voltage is 650 volts, the peak-to-peak voltage is 1300 volts.

Instantaneous Value The instantaneous value is the value at any one particular time

along a sine wave. Instantaneous voltage is equal to the peak

voltage times the sine of the angle of the generator armature.

The sine value is obtained from trigonometric tables. The

following table shows a few angles and their sine value.

The instantaneous voltage at 150° of a sine wave with a peak

voltage of 650 volts, for example, is 325 volts (650 x 0.5).
