Question
If the electric field inside a capacitor exceeds the
dielectric strength of the dielectric between its plates,
the dielectric will break down, discharging and
ruining the capacitor. Thus, the dielectric strength is
the maximum magnitude that the electric field can
have without break-down occurring. The dielectric
strength of air is 3.0 x 10 V/m, and that of neoprene
rubber is 1.2 x 10 V/m. A certain air-gap, parallelplate capacitor can store no more than 0.041 J of
electrical energy before breaking down. How much
energy can this capacitor store without breaking
down after the gap between its plates is filled with
neoprene rubber? Take the dielectric constant of air
to be 1.0, and of neoprene rubber to be 6.7.
