An electronic flash unit for a camera contains a capacitor with a capacitance of 780 μF. When the unit is fully charged and ready for operation, the potential difference between the capacitor plates is 310 V. A) What is the magnitude of the charge on each plate of the fully charged capacitor? Express your answer using two significant figures. B) Find the energy stored in the "charged-up" flash unit. Express your answer using two significant figures.
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.
