a parallel-plate capacitor (2 plates) is filled with titanium dioxide which has a dielectric constant of 80. the area of each plate is 1 cm^2.
a) what must be the spacing between the plates if one wishes to make a 10^-10 farad capacitor?
b) if the dielectric strength of titanium dioxide is 10^8, what is the maximum chrage that this capacitor can safely store?
dielectric constant kappa = 80
epsilon_0 -- constant = 8.85*10^-12
capacitance C = kappa[(epsilon_0*A)/d] where A is area, given = 1 cm sq, d is distance, unknown.
The Attempt at a Solution
capacitance C = kappa[(epsilon_0*A)/d] where C = 10^-10 farad, kappa = 80, epsilon_0 = 8.85*10^-12 ---> solve for d, d = 0.0708 meters = 7.08 cm
unsure, how does dielectric strength relate to dielectric constant?
what equation should i use, is it similar to one the i used in part a?
