Part a to c Please A budding electronics hobbyist wants to make a simple 1.5 nF capacitor for tuning her crystal radio, using two sheets of aluminum foil as plates, with a few sheets of paper between them as a dielectric. The paper has a dielectric constant of 5.0, and the thickness of one sheet of it is 0.16 mm . Part A If the sheets of paper measure 25 cm × 36 cm and she cuts the aluminum foil to the same dimensions, how many sheets of paper should she use between her plates to get the proper capacitance? Part B Suppose for convenience she wants to use a single sheet of posterboard, with the same dielectric constant but a thickness of 15.0 mm , instead of the paper. What area of aluminum foil will she need for her plates to get her 1.5 nF of capacitance? Part C Suppose she goes high-tech and finds a sheet of Teflon of the same thickness as the posterboard to use as a dielectric. Will she need a larger or smaller area of Teflon than of posterboard?
Dielectric Constant Of Water
Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.
Electrostatic Potential and Capacitance
An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particles. The electric force is the force which acts between two stationary charges. It is also called Coulomb force.
