Find analytical value of charge on the
% coaxial cable capacitor plates
Q = 10*2*pi*L / (log(0.8) - log(0.2)) % find analytical values of the electric field in the
% dielectric
E = Q ./(2*pi*vr*L) El = (s(2:end,1) - s(1:end-1,1))/hr % Find numerical values of electric field (the s contains values of
% electric potential)
En = (s(2,:) - s(1,:))/hr % Just check the integral of the charge (should match the analytical
% value)
Q = sum(En(1:end-1))*hz % find value of the capacitance
C = Q/U % This should produce the voltage U, as this represents the
% integral over r from r_a to r_b (Stokes Theorem)
sum(El)*hr
