Homework Statement
There's an LC circuit that's made of an 31 mH inductor and a planar capacitator. The surface of the plate is 20cm^2 and the distance between the plates is 1 cm. What is the electrical permittivity of the insulator between the plates , if the peak current is 0,2mA and the peak voltage 10V
L=31mH=3.1*10^-2 H
A=20cm^2=2*10^-3 m^2
d=1cm=0,01 m
Imax=0,2mA=2*10^-4 A
Vmax=10V
