An ebomiote rod (K = 3), 6 mm thick is introduced between the plates of a parallel plate capacitor of plate area `4xx10^(-2) m^(2)` and plate separation 0.01m. Find the capacitance.

Text Solution

Verified by Experts

Here, `t = 6mm = 6xx10^(-3) m`
`A = 4xx10^(-2) m^(2), d = 0.01m, K = 3`
`C = (in_(0) A)/(d - 1 (1-(1)/(K))) = (8.85xx10^(-12)xx4xx10^(-2))/(0.01-6xx10^(-3)) = 59xx10^(-12) F = 59 pF`
