A capacitor, C1, with a capacitance of 8.0 uF is charged by applying a potential difference of 240 V. After it has been fully charged, it was disconnected from the source of potential difference. What is the charge of the capacitor, C1, when it has been fully charged? What is the energy stored in capacitor, C1, when it has been fully charged? After the situation described above, an uncharged capacitor, C2, with a capacitance of 4.0 uF is connected in parallel to the fully charged capacitor, C1. What will now be the potential difference in capacitor, C1? What will be the potential difference in capacitor, C2? What will now be the charge in capacitor, C1? What will be the charge in capacitor, C2? What will now be the amount of energy in capacitor, C1? What will be the amount of energy in capacitor, C2? What will now be the total energy of the system/circuit? Did the total energy of the system/circuit increase as a result of the addition of capacitor, C2?
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.
