Problem

A leaky parallel-plate capacitor is completely filled with a material having dielectric constant

K=5

and electrical conductivity

\sigma=7.4\times10^{-12}\,\Omega^{-1}\text{m}^{-1}

. If the charge on the capacitor at

t=0

q_0=8.55\,\text{C}

, calculate the leakage current at

t=12\,\text{s}
