Two circular metal plates with 15 cm radius are connected to either side of a 75 V battery. The plates are separated by 5 mm. The battery is then disconnected and replaced with a wire that has a resistance 500 kiloohms. (a) Calculate the charge that the battery sends to each plate. (b) Calculate how long it will take the capacitor to discharge to 2 nC.
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.
