The plates of a paraller-plate capacitor are made of circular discs of radii` 5.0`cm each .If the separation between the plates is `1.0`mm,What is the capacitance?
Text Solution
Verified by Experts
Area of the plate `A = pie r^(2) = pie xx (5 xx 10^(-2))^(2)` `d = 1.0 xx 10^(-3) m ` `C = eplision_0 A / d` `= 8.8 xx 10^(-12) xx 3.14 xx 25 xx 10^(-4) / 10^(-3)` `= 695 xx 10 ^(-5) mu F`
