Tries 0/8 2 What is the electric field amplitude at a distance of 2.5 m from a 70 W lightbulb? Assume all the power of the bulb goes into light of a single color with = 500 nm and assume the bulb produces a spherical wave.
Sparks occur when the electric field in air exceeds 3 x 106 N/C. This is because free electrons normally present in air are accelerated to such high speeds that their kinetic energy will overcome the potential energy holding other electrons to atoms. When those electrons rearrange themselves after such a collision, a flash of light is emitted. Let us suppose that the work done on an electron must give it an energy of 3 x 10-19 J to cause this ionization. How...

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?
