Electric potential at a point in an electric field is the amount of work done in bringing a unit positive charge from infinity to that point. Potential difference between two points is the work done in moving a unit positive charge from one point to the other against the electric field.

Coulomb's law states that the force between two point charges is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between their centers. It can be applied to calculate the forces between multiple charges using the principle of superposition, which states that the net force on a charge due to a system of charges is the vector sum of the individual forces exerted by the other charges on it.

Electric flux is the measure of the electric field passing through a given area. Gauss's theorem states that the total electric flux through a closed surface is equal to the net charge enclosed by the surface divided by the permittivity of the medium.

<p>The electric field due to a dipole is the vector sum of the fields due to the positive and negative charges. The torque experienced by a dipole in a uniform electric field is given by the product of the electric dipole moment and the electric field strength.</p> Signup and view all the answers

<p>Capacitance is the ability of a system to store electric charge. In electrostatics, capacitance is used to quantify the amount of charge that can be stored per unit potential difference in a system, such as a capacitor.</p> Signup and view all the answers
