If the electric field inside a capacitor exceeds the dielectric strength of the dielectric between its...
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 at the maximum magnitude that the electric field can have without breakdown occurring. The dielectric strength of air is 3.0x106 V/m and that of neoprene rubber is 1.2x107 V/m. A certain air gap parallel plate capacitor can store no more than 0.075 J of electrical energy before breaking...

An electron is initially at rest in a uniform electric field having a strength of 1.95 × 106 V/m. It is then released and accelerated by the presence of the electric field. What is the change in the electron’s kinetic energy, in kiloelectron volts, if it travels over a distance of 0.25 m in this field? Over how many kilometers would it have to be accelerated in the same electric field to increase its kinetic energy by 65 GeV? &...
