Answer / chitalima c christopher

the RMS value of an AC quantity is that value which will
produce the same heating efect as a DC QUANTITY

Answer / ullas k prabhu

RMS Value of any quantity =
(Max. value of the quantity)/1.414

Answer / raj

RMS Value means root mean value of AC.

it's normaly 70% of peck value.
like 314V ac having only 220V.

Answer / arindam

RMS VALUE = RMS value of the AC quantity is the same amount
of DC quantity produceing same amount of heat as when AC
current flow.

Answer / santhosh

it is abrivated as root mean square value . it is a steady
state value .heat produced in ac network and dc network are
same in the same circuit at the same time

Answer / anusha

In mathematics, the root mean square (abbreviated RMS or
rms), also known as the quadratic mean, is a statistical
measure of the magnitude of a varying quantity. It is
especially useful when variates are positive and negative,
e.g., sinusoids.

It can be calculated for a series of discrete values or for
a continuously varying function. The name comes from the
fact that it is the square root of the mean of the squares
of the values. It is a special case of the power mean with
the exponent p = 2.

Answer / prabhu

0.707

Answer / shashi kant

Simply speaking, the root-mean-square (RMS) value of an
alternating voltage is the equivalent d.c. voltage that can
deliver the same amount of Energy to a resistor as the a.c.
does over a cycle

Answer / priya

rms value is root mean square. it is measure of ac current
with regards to the heating effect produced by passage of
current.
