Question : 24

Total: 37

What is the area of the plates of a 2 F parallel plate capacitor, given that the separation between the plates is 0.5 cm?

Solution:

C =

ε0A

or A =

C.d

ε0

2×0.5×10−2

8.85×10−12

orA = 1.13 × 109m2 = 1130 km2
This is why ordinary capacitors are in the range of µF or less.
