An inductor,a resistor,and a capacitor are joined in series with an $AC$ source. As the frequency of the source is slightly increased from a very low value,the reactance of the

$A$ coil has an inductance of $2 \ H$. The ratio of its reactance,when it is connected first to an $AC$ source and then to a $DC$ source,is

An alternating voltage $E = 200 \sqrt{2} \sin(100 t) \text{ V}$ is connected to a $1 \mu\text{F}$ capacitor through an $A.C.$ ammeter. The reading of the ammeter shall be: (in $\text{ mA}$)

$A$ $70 mH$ inductor is connected to a $220 V, 50 Hz$ $AC$ supply. The rms value of the current in the circuit is:

Same current is flowing in two different $A.C.$ circuits. The first circuit contains only an inductance $(L)$ and the second contains only a capacitance $(C)$. If the frequency of the $A.C.$ source is increased in both circuits, what will happen to the current?

Obtain an equation for the current when an $AC$ voltage is applied to an inductor and draw a graph of $V$ and $I$ versus time.
