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?

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 a thermosetting polymer is 35000 V/mm. Calculate the thickness of insulation on a cable working at 28 kV to sustain the breakdown. When the same polymer is inserted in a 9 cm2 parallel plate capacitor with a distance between plates of 0.1 mm, a capacitance of 10–3 μF is noticed. Determine the dielectric constant of the polymer.

Question 14 Mica capacitors are commonly used, high-precision capacitors in which the gap between the metal plates is filled with the dielectric material, mica. Considera typical 100 pF mica capacitor (1pF 10-12F). Assuming that the dielectric strength of the material is 118MV- 1.18 x 108 V, and that the thickness of the mica in the capacitor is 25.7 μm thick φ1m-10-6m). (The dielectric strength is the maximum electric field that the material can withstand without breaking down.) Calculate the maximum...

A parallel plate capacitor is composed of two lossy media with relative dielectric constant &ri 12 and 82 3.5, and thickness di 1.5mm and d 3.5mm. Lossy nature manifests itself through a steady-state leakage current with the normal component Jn flowing across the interface between the two dielectric media which have electrical conductivity o1 2x 10-3 and a2 = 5 x 104 S/m, respectively. The two media have dielectric strength EMaxt = 60 MV/m and EMax2 25 MV/m respectively, where...
