Question { IOCL, 39096 }

what is the meaning of rms value

Answer

consider a resistor of r ohms.give ac supply of v1 volts to
it for a time period of t seconds.due to the current
flowing through it the resistor will produce some heat q1
joules.
then the rms value of v1 is the dc voltage required to
produce q1 joules in the same time t seconds in the
resistor r ohm.
