The equation KA - UA = Kb- Ug is also known as the Law of the Conservation of Mechanical Energy.

2. The value of k, or Coulomb's constant, is 90 X 108 Nm2/C

Electric potential and electric potential energy are similar terms.

The voltage present in a battery is equivalent to the difference in potential Vab = Vb + Va between the

positive and the negative terminal points of the battery.

An electron volt (eV) is equivalent to the product of 1 volt and 1 elementary charge.

6. The electric potential due to a point charge is given by V = 1 r / 4 π Eo q

Electric field lines and equipotential surfaces are always perpendicular to each other.

The amount of work in an equipotential surface is equal to zero.

Equipotential surfaces and Gaussian surfaces are similar terms.

In the equation W = Fdcos0, the 0 refers to the angle between the electrostatic force and displacement.
