Answer to Question #300440 in Electric Circuits for Dan

Question

Calculate the capacitance of a capacitor with separation distance of 800m with an area 1.25kmsquare.The permittivity of free space is 8.892*10^-13

Answer 1

Explanations & Calculations

• This just needs the formula for the capacitance defined in terms of gap, area and permittivity.

$\qquad\qquad \begin{aligned} \small C&=\small \epsilon\frac{A}{d}\\ &=\small \epsilon_0.\frac{Area}{gap} \end{aligned}$

• Just substitute all the given values into correct variables in IS units (km in meters) and get the answer
