The alternating current is given by
${i}=\left\{\sqrt{42} \sin \left(\frac{2 \pi}{{T}} {t}\right)+10\right\} {A}$
The $r.m.s.$ value of this current is ${A}$
$11$
$13$
$9$
$15$
In an $A.C.$ circuit, $I_{\text {rms }}$ and $I_{0}$ are related as
An alternating voltage $V = 300\sqrt 2 sin(100t)$ is connected to a $1\ \mu F$ capacitor through an $AC$ ammeter. The reading of the ammeter will be.....$mA$
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 $I_1, I_2, I_3$ and $I_4$ are the respective $r.m.s$. values of the time varying currents as shown in the four cases $I, II, III$ and $IV$. Then identify the correct relations.
Alternating current can not be measured by dc ammeter because
