a parallel-bladed capacitor has an inter-plate length of 1.5 cm and an area of 25 cm2. After these plates are loaded with 250 V, they are disconnected from the source. then the condenser is immersed in distilled water. a) Find the load on the plates before and after immersion in distilled water. b) Find the capacitance and potential difference after immersion in distilled water. c) Find the change in capacitor value. (Take the dielectric constant of distilled water as K = 80)
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.
