You build a home made capacitor using two 9in (22.86cm) diameter metal pie plates that are initially separated with air by a distance of 0.5cm. (make sure to carry at least three digits throughout the problem) (a) What is the capacitance of the system? pf (b) To store 5 microjoules, what potential voltage would you need to charge the capacitor with? (c) That is a lot of volts! You want to store the same 5 microjoules, but use a 120V source to charge it with. What value of a dielectric material would you need to fill the gap? (d) You build and test your homemade capacitor and find it will only store 1 microjoule. To obtain the 5 microjoules you need, how many of the homemade capacitors would you need to make? (e) Would you put them in series or in parallel with the source? O a combination of both O series O parallel

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.
