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...

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?

Problem 2 (25pts). (a) The maximum allowed potential difference for a parallel plate capacitor is given as 150 000 V. Air breaks down at an electric field strength of 3.00x10 V/m. Given that the plates of the capacitor are separated by 0.500 cm of air, would your capacitor break down when charged to its maximum voltage? (b) An electron is accelerated from rest by a uniform electric field through a distance of 0.400 m and emerges with a final kinetic...

An uncharged spherical conductor has a radius of 2.4 m. What is the maximum charge you can deposit on the sphere before dielectric breakdown of the air around it occurs? -> determine the strength of the electric field at the surface of the conductor and compare it against the field strength of 3 × 106 V/m above which air becomes a conductor
