The current and $EMF$ through an inductance differ in phase by

$A$ capacitor of capacitance $10 \mu F$ is connected to an $AC$ source and an $AC$ Ammeter. If the source voltage varies as $V = 50 \sqrt{2} \sin 100 t$, the reading of the ammeter is (in $\text{ mA}$)

Capacitive reactance of a capacitor in an $AC$ circuit is $6 \ k\Omega$. If the same capacitor is connected to an $AC$ source of double the frequency,the capacitive reactance will become

When an a.c. source is connected across a pure resistor,the correct phase relation between current $(i_R)$ and voltage $(e_R)$ is shown in which figure?

$A$ $100 \mu F$ capacitor is connected to a $100 \text{ V}$, $50 \text{ Hz}$ $AC$ supply. The rms value of the current is (in $\text{ A}$)

In an $AC$ circuit containing only a capacitor,how does the current relate to the potential difference?
