An electronic flash unit for a camera contains a capacitor witha capacitance of 750 mF. When the unit is fully charged and readyfor operation, the potential difference between the capacitorplates is 360 V. (a) What is the magnitude of the charge on eachplate of the fully charged capacitor? (b) Find the energy stored inthe “charged-up” flash unit.
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.
