RMS value is the value of root of square of posiitive and
negative both values and it is positive while average may
be negative or zero also. RMS value of a sine wave of
amplitude 1 is 1/sqrt(2) while its average is zero.

Answer / 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.

Answer / ashok meena

RMS value is equal to the product of foam factor (1.11)and
avg. value .
foam factor = (rms value/avg value) = 1.11
avg. value is actual output but for all computational work
we required rms value. thts y the rating is give in te for
off rms value .

Answer / waqas

RMS value is Root of mean of the square of a sinusoidal signals instantaneous value.
Average value is sum of negative and positive side of a DC signal wave.
Average value for AC signal is always zero because half cycle of sinusoidal is +ve And half cycle is -ve so its sum will always be zero

Answer / rishikesh sawale

The voltage at which heat dissipation in ac circuit is equal to heat dissipation in dc circuit is the RMS value.

and

The voltage at which charge transfer in ac circuit is equal to charge transfer in dc circuit is average value.
