A capacitor stores charge Q at a potential difference AV. If the voltage applied by a battery to the capacitor is doubled to 2AV, which of the following happens? O the capacitance and the charge both fall to half their initial values O the capacitance falls to half its initial value and the charge remains the same O the capacitance and the charge both double O the capacitance remains the same and the charge doubles
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.
The relation between the charge, capacitance and voltage is given by
Q = C V
where, Q is the charge, C is the capacitance and V is the voltage.
