Question

What is meant by mean voltage?
Is RMS voltage and mean voltage the same thing?

Answer 1

these are same... when the function of voltage or current is varying with time ...or you can say a time dependent function ...then we need to find out the mean ..in which we use root mean square formula to find out the mean of quantity...over a time interval

Answer 2

akshat.. hope your doubts decrease.

Answer 3

Thanks a lot guys! :)

Answer 4

Technically, the arithmetic mean voltage of a typical sinusoidal AC source is 0V. In contrast, the RMS voltage is calculated based on the standard deviation about the mean and will therefore always be greater than or equal to the mean.

In most day-to-day applications, true RMS values are not needed and the "average voltage" is used instead which is calculated as 0.636 x peak voltage. This is what most voltmeters read unless they are specifically designed to calculate true RMS...in which case they are usually a bit more expensive.
