For an $A.C.$ current $I = 100 \sin(200 \pi t)$,after what time does the current reach its maximum value?

An alternating current is given by the equation $i = i_{1} \sin \omega t + i_{2} \cos \omega t$. The rms current will be

An electric current has both $DC$ and $AC$ components. The $DC$ component is $8 \ A$ and the $AC$ component is given as $I = 6 \sin \omega t$. The $rms$ value of the resultant current is . . . . . . (in $A$)

In an $AC$ circuit,the current is given by $I = 100 \sin(200 \pi t)$. The time required for the current to achieve its peak value will be:

One complete set of negative and positive values of alternating quantities is called

The mean and $rms$ value of an alternating voltage for a half cycle,as shown in the figure,are respectively:
