Answer Posted / javad ahamad
rms value is expressed in terms of dc. suppose we have a
simple resistive ckt. first we connected a dc source and
applied a certian voltage then noticed the heat produced
in the resistor.then we replae the source by ac and we
adjusted the souce to such a value that it produce the
same heating affect when the dc is applied.that value is
called rms value of ac.
rms value is less than peak vale.
