To get the average:
Volts avg=0.637 X Vp (peak)
0.637 X 80 Vp = 50.96 Vavg
To get rms (root mean square):
Volts rms = 0.707 X Vp (peak)
0.707 X 80 Vp = 56.56 Vrms
CommentIt should be pointed out that the average value, described above, is for half a cycle. The average for a complete cycle is zero.
RMS value of 80 VAC is 56.56. Peak x 0.707 = RMS, RMS x 1.414 = Peak
He wants to know the average not the RMS value. The values are not he same. Look it up.
AnswerThe average value of an a.c. voltage is zero.
Peak inverse voltage of a device like diode gives the maximum value of voltage that it can withstand without being damaged when it is reverse biased.
RMS is used to determine the average power in an alternating current. Since the voltage in an A/C system oscillates between + and -, the actual average is zero. The RMS or "nominal" voltage is defined as the square root of the average value of the square of the current, and is about 70.7% of the peak value.************************************************************The r.m.s. value of an alternating current or voltage is the value of direct current or voltage which produces the same heating effect.Fo a sine wave, the r.m.s. value is 0.707 x the peak value.The average value is different; for a sine wave it is 0.636 x the peak value.
You are, presumably, referring to alternating current, in which case the 'maximum' current is the peak or amplitude of the waveform. The 'average' value of current is zero, because the average value of the first half of each cycle is negated by the average value over the second half of each cycle. This is why a.c. currents and voltages are always expressed in 'root-mean-square' (r.m.s.) values which is the value of an a.c. current that does the same amount of work as a given value of d.c. current. The r.m.s. value for a sinusoidal current (and voltage, as voltage and current are proportional) is 0.707 times the peak or maximum value.

A.C. voltages or currents are always quoted in rms values unless otherwise specified.The average value of an a.c. voltage or current is zero over one complete cycle so, when used, it applies only over one half cycle. Therefore, the average value for one-half cycle of a sine wave is 0.637 times the peak value. Average values are of little relevance to a.c. calculations.
ANSWER: The peak to peak voltage can be found by multiplying 120 v AC x 2.82= 339.41
It is the highest value of the amplitude, called the peak value. Scroll down to related links and look at "RMS voltage, peak voltage and peak-to-peak voltage". Look at the figure in the middle below the headline "RMS voltage, peak voltage and peak-to-peak voltage".

The RMS value of an AC voltage is VRMS = VPEAK / sqrt(2), where VPEAK = the voltage peak to neutral.AnswerThe average value of a sinusoidal a.c. voltage is zero.
When the AC waveform goes to one peak, the capacitor that follows the diode is charged to that peak value. When the AC waveform goes to the other peak, the same diode is reverse biased between the alternate peak value and the charged value of the capacitor. This differential voltage is two times peak voltage.

When you say holdhold supply of 230volts, you are referring to the RMS value, not the peak value.
Conversions of RMS voltage, peak voltage and peak-to-peak voltage. That are the used voltages. The expression "average" voltage is used for RMS voltage.Scroll down to related links and seach for "RMS voltage, peak voltage and peak-to-peak voltage".Answer'Average' is not the same as 'root mean square'. As the average value of a sinusoidal voltage is zero, you cannot convert it to a peak-to-peak value.
Another name for average voltage is the RMS (Root Mean Square). This is a voltage derived from the peak to peak voltage multiplied by .707. If the peak to peak voltage is 170 volts then the average voltage (RMS) would be 170 x .707 = 120 volts.
