The charge of a parallel plate capacitor is varying as

q=q_0 \sin 2 \pi v t

. The plates are very large and close together. Neglecting edge effects, the displacement current through the capacitor is

Options

A $\frac{q}{A \varepsilon_0}$
B $\frac{q}{\varepsilon_0} \sin 2 \pi v t$
C $2 \pi v q_0 \cos 2 \pi v t$
D $\frac{2 \pi v q_0}{\varepsilon_0} \cos 2 \pi v t$

Correct answer

C. $2 \pi v q_0 \cos 2 \pi v t$

Step-by-step solution

I=\frac{d q}{d t}=\frac{d}{d t}\left(q_0 \sin 2 \pi v t\right)=q_0 2 \pi v \cos 2 \pi v t
