How can we define electric potential at any point?

Explanation

To define electric potential at any point, we can follow these steps:

### Step 1: Understanding Electric Potential
Electric potential at a point in an electric field is defined as the amount of work done in bringing a unit positive charge from a reference point (usually taken as infinity) to that point without any acceleration.

### Step 2: Work Done in Bringing Charge
When we bring a unit positive charge (let's denote it as +1 coulomb) from infinity to a point P in the electric field, we need to consider the work done against the electric field. This work done is what defines the electric potential at point P.
