Question

Consider a simple parallel plate capacitor with an area of 19E-5 sq. m. Determine (a) the capacitance when storing a charge of 7E-5 C with a potential of 7kV. (b) Determine the separation distance and minimum dielectric strength if plates are separated by a material with a dielectric constant of 1. (c) Determine the separation distance and minimum dielectric strength if plates are separated by material with a dielectric constant of 3000 .

(a) C = _______________

(b1) d= ____________ (b2) DES = _______________

(c1) d= ____________ (c2) DES = _______________

Answer 1

(a). C=1x10^-3F

(b1). d=1.6815x10^-7m

(b2) DES= 1x10^-3 V/m

(c1). d=1.6815x10^-7m

(c2) DES= 3 V/m

Let us consider the numerical values of the area of the parallel plate capacitor and the charge same as in electron value like area A= 19E-5 and Charge 7E-5.
