Answer / tahan_89

it is the average value in the sinusoidal waveform we can get it by dividing the peak value by root 2

Answer / ratnagiri

RMS is nothing but Root Mean Square Value.

Answer / raghu

imagine a dc current flowing in a resistive ckt.. it
produces (i^2)*R heat.. now imagine ac current in the same
ckt.. find out the power dissipated in the network by
integrating the sum of the squares of the instantaneous
values of the current under root.. and equate it to the
power dissipated by dc current.. the value obtained is rms
value..

is there any chance to get shock from the transformer oil at the time of maintenance due to its dielectric property. . ?

1. If we apply dc supply to the primary winding of transformer it will be burnt out. similarly dc supply is given to field winding of syn. motor and armature winding of dc motor, they are safe. (Remember both windings inductive nature) what is the reason behind that?
