An alternating voltage $E = 200\sqrt 2\, \sin\, (100\,t)$ is connected to a $1$ microfarad capacitor through an ac ammeter. The reading of the ammeter shall be......$mA$

If $i = {t^2}$ $0 < t < T$ then $r.m.s$. value of current is

An alternating voltage is given by : $e = e_1\, \sin \omega t + e_2\, \cos \omega t$. Then  the root mean square value of voltage is given by :-

Three alternating voltage sources $V_1$ = $3 sin \omega t $ volt , $V_2= 5  sin(\omega t + \phi _1)$ volt and $V_3 = 5  sin(\omega t -\phi_2 )$ volt connected across a resistance $R= \sqrt {\frac{7}{3}} \Omega $ as shown in the figure (where $ \phi_1$  and $ \phi_2$   corresponds to $30^o $ and $127^o $ respectively). Find the peak current (in Amp) through the resistor

In general in an alternating current circuit

In alternating current circuits, the $a.c$. meters measure
