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.
1. On the spherical equipotential surfaces of a positive point charge, point A and C are located on the same surface while point B is located on another one. If the potential difference is 3.00 V between the surfaces where points A and B are located, what is the work done by the electric field in moving a positive test charge (+q) from A to B, and then to C?
2. A dipole with magnitude 3Q is placed inside the cavity of the solid conductor with net charge +7Q. What is the total charge at the outer surface of the conductor?
3. A 2.0 Ω resistor is connected to a non-ideal source with internal resistance equal to 1.0 Ω and EMF equal to 15V. If the potential measured by the voltmeter across the resistor is 10V, find the rate of electrical energy dissipation in the battery.
