(a) the potential difference between the plates (b) the initial stored energy (c) the final stored energy (d) the work required to separate the plates
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.
The parallel plates in a capacitor, with a plate area of 9.60 cm2 and an air-filled separation of 4.00 mm, are charged by a 3.90 V battery. They are then disconnected from the battery and pulled apart (without discharge) to a separation of 9.40 mm. Neglecting fringing, find:
(a) the potential difference between the plates
(b) the initial stored energy
(c) the final stored energy
(d) the work required to separate the plates
Please explain the steps you are taking and the unit conversions you are doing at each point. I am setting up the problem correctly but the unit conversions are tripping me up.
