The dielectric strength of air (that is, the maximum electric field air can withstand before it becomes a conductor due to ionization) is 3.0 times 10^6 V/m. Small van de Graaf generators are commonly used in hair-raising demonstrations that must achieve a high electric potential. A spherical conductor has a radius of 30 cm (about 1 ft). What is the maximum charge that can be placed on the sphere before dielectric breakdown of the surrounding air occurs? For the charge...

The dielectric strength of air, E = 3.0×106 V/m, is the maximum field that air can withstand before it breaks down and becomes conducting. How much charge can be placed on a spherical conductor with a 8.0- cm radius before the field at its surface exceeds the breakdown strength of the air? The answer to this section is 2.14×10-6 C. My question: What would be the electric potential at the surface of this conductor?

1. Square wave guide Consider
a waveguide that is filled with a dielectric that undergoes
breakdown (sparking) at an electric field of 10 kV/m. Calculate the
maximum power that can be carried by the TE1,0 mode without
breakdown if the dimensions of the wave guide are 5 cm by 5 cm.
Assume that the frequency is twice the cutoff frequency. Your may

If the magnitude of an electric field in air is as great as 3.00×106 N/C, the air becomes ionized and begins to conduct electricity. This phenomenon is called dielectric breakdown. A charge of 23.6 μC is to be placed on a conducting sphere. What is the minimum radius of a sphere that can hold this charge without breakdown?
