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 $\left( {{t_0} > > \frac{L}{R}} \right)$
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 $AC$ current is given by $I = I_0 + I_1$ $sin\, wt$ then its $rms$ value will be
Give definition and formula of root mean square plot graph of current versus $\omega t$.
Two cables of copper are of equal lengths. One of them has a single wire of area of cross-section $A$, while other has $10$ wires of cross-sectional area $A / 10$ each. Give their suitability for transporting $A.C.$ and $D.C.$
