Definition of Absolute Potential: The absolute potential at a point in an electric field is defined as the amount of work done by an external force in bringing a unit positive charge from infinity to that point without any acceleration.

Calculation of Electric Potential due to a Point Charge: The electric potential (V) due to a point charge (q) at a distance (r) from the charge in a vacuum or air is given by the formula:

V = k*q/r

Here, k is Coulomb's constant, whose value is approximately 8.9910^9 Nm^2/C^2.

This formula states that the electric potential decreases as we move away from the charge and vice versa. It is positive for positive charges and negative for negative charges.

The electric potential is a scalar quantity and its unit is volt (V). It can also be defined as the work done per unit charge.

It's important to note that the electric potential at a point due to a system of charges is the algebraic sum of the electric potentials due to individual charges.

This is how we define absolute potential and calculate the electric potential due to a point charge.
