Two parallel plates that are initially uncharged are separated by 1.7 mm and have only air between them. Each has a surface area of 16 cm2. How much charge must be transferred from one plate to the other if 1.9 J of energy are to be stored in the plates? Hint: You do not know the potential difference between the plates, so choose an expression for the stored energy that only has the charge Q and capacitance C in it. Calculate the capacitance from the plate area and separation. Standard units! Group of answer choices
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.
