What is the difference between RMS and average value
Answer Posted / padam singh
RMS value is the root of the average of the square of the
instantaneous value of any wave. Being the squared it comes
always in positive value. It plays important role in
representing the value of sine wave (Mains voltage
specifically).It's value for a sine wave is equal to Peak
votage/sqrt(2). However average value is the simple average
of any wave. It comes positive for positive half and
negative for negative half of a sine wave. It's value is
Peak voltage/Pie for one half only and zero for a complete
sine wave. Generally AC Voltage is represented in terms of
RMS value.
