Parallel Plate Capacitor A parallel plate capacitor consists of square plates 0.

Question

Parallel Plate Capacitor A parallel plate capacitor consists of square plates 0.10 meters on a side and with a distance of 0.15 millimeters between them. What is the capacitance of the component in Farads? 1.1 nano-Farads 970 pico-Farads 590 pico-Farads 240 pico-Farads Spherical Capacitor A capacitor is made from two exactly concentric spherical shells conducting shells where the radius of the inner shell is 1.0000 meters and the radius of the outer shell is 1.0100 meters. What is the capacitance of the arrangement?

Explanation / Answer

13 ans

Given that

area A=0.10^2=0.01 m^2

distance d=0.15*10^-3 m

now we find the capacitance

capacitance C=eA/d=8.85*10^-12*0.01/0.15*10^-3

=0.59 nF

=590 pF
