Q. In a parallel plate capacitor , the capacity increases if
A) Area of the plate is decreased
B) Distance between the plates increases
C) Area of the plate is increased
D) Dielectric constant decrease
Explanation
(c) In a parallel plate capacitor, the capacity of capacitor,
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ C = \frac{k\varepsilon_{0}A}{d}$
$\ \ \ \ \ \therefore\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ C\ \propto A$
So, the capacity of capacitor increases if area of the plate is increased.
