I was right. V = Ed ; where E is the electric field needed to conduct teflon and d is the distance between the parallel plates. the electric field needed to break down teflon is 60 kV/mm so (60 kV/mm) * (0.06 mm) = 3.6 kV. You must raise the potential difference of the parallel plates to 3600...
C = epsilon_0 * A * K / d where K is the dielectric constant of Teflon (2.1)
(so just multiply the answer you got by 2.1)
the dielectric breakdown of Teflon according to the website below is 60 kV/mm so I think your answer to b) is:
V = Ed --> (60 kV/mm) * (0.06 mm) = 3.6 kV. Could you...
