Answer to Question #187454 in Electricity and Magnetism for Daniel

Question

Determine the permittivity of a dielectric within a capacitor stores 60 Mf worth or charge has an area of 0.5 m² for each plate and 2.0 X 10^-⁴ m apart.

Answer 1

Answer

Capacitance is given by

$C=\frac{\epsilon _0KA}{d}$

K is permittivity of dielectric medium.

$K=\frac{Cd}{ A \epsilon _0 }\\=\frac{60\times10^{-6}\times 2.0 \times10^-⁴ }{ 0.5\times8.85\times10^{-12}}\\=2711.86$
