Question

if the peak value of alternating current is 15V what is its mean value over half cycle​

Answer 1

Answer:

RMS Voltage to Peak-to-Peak Voltage Formula

Using RMS voltage, the peak voltage can be found using this formula where VRMS is RMS voltage. So, peak-to-peak voltage is equal to two times the square root of two times RMS voltage. For example, let's find the peak-to-peak voltage using 75 V RMS voltage.
