What is the area of the plates of a 3F parallel plate capacitor, if the separation between the plates is 5mm

$1.694 \times 10^{9} \, m^{2}$

$4.529 \times 10^{9} \, m^{2}$

$9.28 \times 10^{9} \, m^{2}$

$12.981 \times 10^{9} \, m^{2}$

Text Solution

Verified by Experts

The correct answer is:

We have $C = \frac{\varepsilon_0 A}{d}$ ⇒ ⇒ $A = \frac{Cd}{\varepsilon_0} = \frac{3 \times 5 \times 10^{-3}}{8.85 \times 10^{-12}}$

$= 1.7 \times 10^{9} m^{2}$
