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?

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 $\text{ mA}$)

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 alternating e.m.f. is increased,the values of current will

$A$ $15.0 \; \mu F$ capacitor is connected to a $220 \; V, 50 \; Hz$ source. Find the capacitive reactance and the current ($rms$ and peak) in the circuit. If the frequency is doubled,what happens to the capacitive reactance and the current?

In a circuit containing a pure resistor connected to an $AC$ source,

An alternating voltage $E = 100 \sqrt{2} \sin(50 t)$ is connected to a $2 \mu F$ capacitor through an a.c. ammeter. The ammeter reading will be (in $\text{ mA}$)
