An air capacitor is madeby using two flat plates, each with
area A, separated by a distanced . Then a metal slab having
thickness a (less than d )and the sameshape and size as the plates
is inserted between them, parallel tothe plates and not touching
either plate.
a) What is the capacitance of this arrangement?
C = C0 d/(d-a)
b) Express the capacitance as a multiple of the
capacitanceC0 when the metal slab is not present?

A capacitor is constructed from two square, metallic plates of sides land separation d. Charges +Qand-Q are placed on the plates, and the power supply is then removed. A material of dielectric constant x is inserted a distance x into the capacitor as shown in the figure below. Assume d is much smaller than x. Suggestion: The system can be considered as two capacitors connected in parallel. (Use the following as necessary: 80, X, 1, Q. d, and x.) +...

A flat plate (k-1 W/m-K, p 2 kg/m3, c 0.7 kJ/kg-K) separates two fluids with different temperatures and convection coefficients. Heat conduction in the plate can be considered one-dimensional. The initial temperature of the plate is uniform and equal to 30 °C. a) Select the problem parameters using the table below. b) Cover the domain with a grid and write the finite...

Written Question #1: Storm clouds may build up large negative charges near their bot- tom edges. The earth is a good conductor, so the charge on the clouds attract positive charges on the earth under the cloud. The electric field strength near the earth de- pends on the shape of the earth's surface, as we can explain with a simple model. The top metal plate in the figure has a uniformly distributed negative charge. The bottom plate is overall neutral...
