Question

Mica capacitors are commonly used, high-precision capacitors in which the gap between the metal plates is filled with the dielectric material, mica. Consider a typical 100 pF mica capacitor (1pF 10-12F) Assuming that the dielectric strength of the material is 118 M 1.18 x 10s V, and that the thickness of the mica in the capacitor is 36.9 μ m thick (1 μm-10-6m), calculate the maximum allowed voltage for this capacitor before dielectric breakdown occurs. (Assume that the electric field inside the capacitor can be approximated as being uniform.)

Answer 1

Since we know that

V = Ed   

V = 1.18 X 10⁸ X 36.9 X 10^-6

^{V = 4354.2 volt      Ans}
