O$$JECTIVE: Calculate capacitance based on physical and electrical parameters.

Part A:

Given the table of dielectric constants shown to the

right, determine the capacitance for each of the

capacitors listed below. If a voltage of $12$ V is

applied, determine the amount of charge stored in

the capacitor.

A capacitor with round plates of diameter

$20$ mm separated by a distance of $0\mathrm{.}01$ mm

using a dielectric of porcelain.

A capacitor with square plates of $1$ m

separated by a distance of $0\mathrm{.}1$ mm using a

dielectric of air.

Part B:

Design a capacitor, using the table shown above and your knowledge of capacitor construction,

that would store a voltage of $10$ V when $25$ mC of charge is stored on one plate. You may use any

material for the dielectric and any shape$/$dimensions you wish to achieve the desired

performance.
