Question

In a parallel plate capacitor, the capacitance increases if

​​​​​​​$[$1 Mark$]$

• A. area of the plate is decreased
• B. distance between the plates is increased
• C. area of the plate is increased
• D. dielectric constant is decreased

Answer 1

The correct option is C area of the plate is increased

In a parallel plate capacitor, the capacitance of a capacitor is given by

$C=\frac{K{ϵ}_{0}A}{d}$

i.e $C\propto A$

As capacitance is directly proportional to area, when area of plate increases capacitance also increases.
