Problem

A resistor

R = 1\,\text{k}\Omega

is connected in series with a parallel plate capacitor. The capacitor is filled with a dielectric of

K = 4

. A

10\,\text{V}

battery is connected at

t=0

. Calculate the time constant of this charging circuit if the capacitor dimensions are

A = 50\,\text{cm}^{2}

and

d = 0.5\,\text{mm}
