A parallel plate capacitor with plates of area $A$ and separation $d$ is connected to a battery of emf $V$. If the capacitor is then disconnected from the battery and a dielectric slab of thickness $t$ and dielectric cons\tant $K$ is inserted between the plates, find the new capaci\tance $C'$ in terms of $A$, $d$, $t$, $K$, and $V$.

Answer Options

Correct Answer A. \frac{AV}{d}\left\( 1+\frac{Kt}{d}\right \)
B. \frac{AV}{d}\left\( 1-\frac{Kt}{d}\right \)
C. \frac{AV}{d}\left\( 1+\frac{Kt}{d^2}\right \)
D. \frac{AV}{d}\left\( 1-\frac{Kt}{d^2}\right \)
Correct Answer
A
Correct Option:
\frac{AV}{d}\left\( 1+\frac{Kt}{d}\right \)
