When charges Q of equal magnitude and opposite sign are placed on the plates of a parallel-plate capacitor of capacitance C, the voltage between the plates is V and the energy stored in the capacitor is U. If C is doubled and Q is not changed, how are V and U affected?
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.
Plesase answer of this question immidiately i will rate you sure.
