A 10 μF parallel-plate capacitor is connected to a 14.0 V battery. After the capacitor is fully charged, the battery is disconnected without loss of any of the charge on the plates. (A) A voltmeter is connected across the two plates without discharging them. What does it read? Express your answer with the appropriate units. (B) What would the voltmeter read if the plate separation were doubled? Express your answer with the appropriate units. (C) What would the voltmeter read if the radius of each plate was doubled, but the separation between the plates was unchanged? Express your answer with the appropriate units.
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.
