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

An alternating current at any instant is given by $i = [6 + \sqrt{56} \sin (100 \pi t + \frac{\pi}{3})] \ A$. The rms value of the current is . . . . . . . (in $A$)

In India,$AC$ voltage becomes zero how many times in $1$ $sec$?

The instantaneous value of an $AC$ is given by $I = 5 \sin (\omega t + \phi) \text{ A}$. The rms value of current is

In general,in an alternating current circuit:

$A$ generator produces a voltage that is given by $V = 240 \sin(120t)$,where $t$ is in seconds. The frequency and $r.m.s.$ voltage are:
