(a) a 20-µF capacitor with a 4-V potential difference between its plates(b) a 30-µF capacitor with charges of magnitude 90 µC on each plate(c) a capacitor with charges of magnitude 80 µC on its plates, differing by 2 V in potential(d) a 10-µF capacitor storing energy 125 µJ(e) a capacitor storing energy 250 µJ with a 10-V potential difference
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.
