Problem

Which of the following expressions gives the capacitance

C

of a parallel-plate capacitor filled uniformly with a dielectric material of constant

\kappa

? a)

C = \dfrac{\epsilon_{0}A}{d}

C = \kappa\epsilon_{0}\dfrac{A}{d}

C = \dfrac{\epsilon_{0}A}{\kappa d}

C = \dfrac{\kappa\epsilon_{0}A}{2d}
