What is the maximum voltage of $220\, V$ ?
In an $ac$ circuit $I = 100\, sin \,200$ $\pi t.$ The time required for the current to achieve its peak value will be
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
What are $DC$ signals and $AC$ signals ? Why do we preferred an $AC$ signal ?
An alternating voltage $v\left( t \right) = 220\,\sin \,100\pi l\,volt$ is applied to a purely resistive load of $50\,\Omega $ . The time taken for the current to rise from half of the peak value of the peak value is.....$ms$
In the given $A.C.$ circuit, the instantaneous current through inductor and capacitor are $0.8 \,A$ and $0.4 \,A$ respectively. The instantaneous current through resistor is ........
