Question

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

Answer 1

`"Here", " "C=2F`
`d=0.5cm=0.5xx10^(-2)m,`
`in_(0)=8.854xx10^(-12)C^(2)N^(-1)M^(-2)`
`C=(in_(0)A)/(d)`
`A=(Cd)/(in_(0))=(2xx0.5xx10^(-2))/(8.854xx10^(-12))`
`A=1.13xx10^(9)m^(2)`
