The value of the current through an inductance of $1 \, H$ and of negligible resistance,when connected to an $ac$ source of $200 \, V$ and $50 \, Hz$ is: (in $, A$)

In a circuit consisting of a capacitance and a generator with alternating emf $E_{g}=E_{g0} \sin \omega t$,$V_{C}$ and $I_{C}$ are the voltage and current. The correct phasor diagram for such a circuit is:

$A$ $10 \mu F$ capacitor is connected to a $210 \text{ V}, 50 \text{ Hz}$ source as shown in the figure. The peak current in the circuit is nearly $(\pi = 3.14)$ : (in $\text{ A}$)

An $A.C.$ voltage is applied to a pure inductor. The current in the inductor

The voltage across a pure inductor is represented by the following diagram. Which of the following diagrams will represent the current?

The same current is flowing in two alternating circuits. The first circuit contains only an inductor and the other contains only a capacitor. If the frequency of the $AC$ emf is increased,what will be the effect on the value of the current?
