Hot wire ammeters are used for measuring
The direct current which would give the same heating effect in an equal constant resistance as the current shown in figure, i.e. the $r.m.s.$ current, is.....$A$
The r.m.s. voltage of domestic electricity supply is $220$ $volt$ . Electrical appliances should be designed to withstand an instantaneous voltage of......$V$
An $AC$ current is given by $I = I_0 + I_1$ $sin\, wt$ then its $rms$ value will be
The process by which $ac$ is converted into $dc$ is known as
