In a parallel plate capacitor with air between the plates, each plate has an area of `6xx10^(-3)m^2` and the distance between the plates is 3 m. Calculate the capacitance of the capacitor. If this capacitor is connected to a 100V supply. What is the charge on the each plate of the capacitor?

Text Solution

Verified by Experts

`C = (epsi_0 A)/(d)`
` C = (8.85 xx 10^(-12) xx 6 xx 10^(-3))/(3 xx 10^(-3))`
`C = 17.7 xx 10^(-12) F`
The charge on each plate is equal and opposite and the charge
Q = CV
` Q = 17.7 xx 10^(-12) xx 100 = 17.7 xx 10^(-10) C = 1.77 nC`
