a parallel plate capacitor is holding 10 C of charge while exposed to a 2V potential difference . How much energy is stored by this capacitor ?
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.
a parallel plate capacitor is holding 10 C of charge while exposed to a 2V potential difference . How much energy is stored by this capacitor ?
In case of a parallel plate capacitor the energy depends on the charge stored and applied potential difference.
Let us consider U is the energy stored by the capacitor. If dU be the amount of energy stored by capacitor when applied voltage is dV,then we can express this by,
Integrating we get,
Moreover, amount of charged stored by the capacitor is proportional to the voltage,
Q=CV
C is capacitance.
