Two conductive plates with an area of 10.0cm x 10.0 cm are held facing one another at a separation of 1.50 mm and 12.0 V is applied between them. a) Find the capacitance of this configuration b) Find the charge on the plates. c) How much energy is stored in the capacitor? d) How much energy can the capacitor store if a dielectric with K= 4.5 is inserted between the plates rather than air?
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.
Batteries and capacitors can be used to store electrical energy. Batteries do this in the form of chemical potential energy whereas capacitors do this with an electric field. Batteries tend to be more stable but capacitors tend to have faster charge and recharge times. A simple capacitor can be constructed from two
a) Find the capacitance of this configuration
b) Find the charge on the plates.
c) How much energy is stored in the capacitor?
d) How much energy can the capacitor store if a dielectric with K= 4.5 is inserted between the plates rather than air?
