A series $LR$ circuit is connected to a voltage source with $V(t) = V_0\,\,sin\,\omega t$ . After very large time,current $I(t)$ behaves as $\left( {{t_0} > > \frac{L}{R}} \right)$
The voltage of an ac source varies with time according to the equation $V = 100\sin \;100\pi t\,\cos \,100\pi t$ where $t$ is in seconds and $V$ is in volts. Then
In an $ac$ circuit $I = 100\, sin \,200$ $\pi t.$ The time required for the current to achieve its peak value will be
Give definition and formula of root mean square plot graph of current versus $\omega t$.
The $r.m.s.$ value of an ac of $50\,Hz$ is $10\,amp$ . The time taken by the alternating current in reaching from zero to maximum value and the peak value of current will be
