The maximum value of $a.c.$ voltage in a circuit is $707V$. Its rms value is.....$V$

An alternating current is given by the equation $i = {i_1}\cos \,\omega \,t + {i_2}\sin \omega \,t$. The r.m.s. current is given by

If ${E_0}$ represents the peak value of the voltage in an ac circuit, the r.m.s. value of the voltage will be

What is the sum of the instantaneous current values over one complete $AC$ cycle ?

In an $ac$ circuit, the instantaneous voltage $e(t)$ and current $I(t)$ are given by $e(t)$ = $5[cos\ \omega t + \sqrt 3\ sin\ \omega t]\ volt$ $i (t)$ = $5[sin(\omega t +\frac {\pi}{4})]\ amp$ then

In a circuit, the value of the alternating current is measured by hot wire ammeter as $10$ ampere. Its peak value will be......$A$
