In a parallel plate capacitor with air ...

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

Text Solution

Verified by Experts

Here, `A = 6xx10^(-3) m^(2), d = 3mm = 3xx10^(-3) m, C = ?, V = 100V, q = ?`
`C_(0) = (in_(0)A)/(d) = ((8.85xx10^(-12))(6xx10^(-3)))/(3xx10^(-3)) = 1.77xx10^(-11) F`
`q = C_(0) V = 1.77xx10^(-11)xx100 = 1.77xx10^(-9)C`
