Electrostatics and capacitors

Define electric field strength

The electric field strength at a point in an electric field is defined as the force per unit positive charge placed at that point.

Define electric potential

The electric potential at a point in an electric field is equal to the work done in moving a unit positive charge placed at that point.

Define capacitance

the charge stored per unit potential difference

what is equipotential?

All points in an electric field that have the same potential can be thought as lying on a surface called the equipotential.

What does Coulomb’s law of electrostatics state?

the force between charges is directly proportional to the product of their charge and inversely proportional to the square of their separation.
