BV-1 An insulator with dielectric constant K-4.50 has a dielectric breakdown strength of 1.25x10 V/m. a) Use this dielectric and find the area A and separation d of two flat metal sheets needed to build a capacitor with C-3.65f with a breakdown voltage of 400V. Hint: Find d first. b) Find the charge magnitude on each plate of the capacitor when it is charged to 399V. c) Find the charge magnitude on each surface of the dielectric when the capacitor is charged to 399V.
