A capacitor in air has a separation between its plates of 1.5 cm and a surface area of plates of 25 cm2. The plates are charged to a potential difference of 250 V and have been disconnected from the power source. The capacitor is immersed in distilled water. Determine a) the charge on the plates before and after immersion, b) the capacitance and the potential difference after immersion.
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.
