The plates of a paraller-plate capacitor are made of circular discs of radii 5.0cm each .If the separation between the plates is 1.0mm,What is the capacitance? |

Answer» SOLUTION :Area of the plate `A = pie R^(2) = piexx (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` |
