A parallel plate capacitor is charged by connecting it to a battery through a resistor. If $$i$$ is the current in the circuit, then in the gap between the plates:
 1 displacement current of magnitude equal to $$i$$ flows in the same direction as $$i$$. 2 displacement current of magnitude equal to $$i$$ flows in a direction opposite to that of $$i$$. 3 displacement current of magnitude greater than $$i$$ flows but can be in any direction. 4 there is no current.

To produce an instantaneous displacement current of $$2~\text{mA}$$ in the space between the parallel plates of a capacitor of capacitance $$4~\mu\text{F}$$, the rate of change of applied variable potential difference $$\left(\frac{dV}{dt}\right)$$ must be:
1. $$800~ \text{V} / \text{s}$$
2. $$500~ \text{V} / \text{s}$$
3. $$200~ \text{V} / \text{s}$$
4. $$400 ~\text{V} / \text{s}$$

A capacitor of capacitance $$C$$ is connected across an AC source of voltage $$V$$, given by;
$$V=V_0 \sin \omega t$$$\mathrm{}$
The displacement current between the plates of the capacitor would then be given by:
1. $$I_d=\frac{V_0}{\omega C} \sin \omega t$$
2. $$I_d=V_0 \omega C \sin \omega t$$
3. $$I_d=V_0 \omega C \cos \omega t$$
4. $$I_d=\frac{V_0}{\omega C} \cos \omega t$$
