**Electric Potential:**

Electric potential is a fundamental concept in physics that describes the electric potential energy per unit charge at a particular point in an electric field. It represents the amount of work done to move a positive test charge from infinity to that point, divided by the magnitude of the test charge.

**Definition of 1 Volt:**

When we say that the electric potential at a point is 1 volt, it means that the work done to move a positive test charge of 1 coulomb from infinity to that point is 1 joule.

**Explanation:**

To understand this concept more clearly, let's consider a simple analogy. Imagine a ball placed on a hilltop. The height of the hill represents the electric potential, and the ball represents the positive test charge.

- As we move the ball downhill, it gains kinetic energy due to the conversion of potential energy.
- Similarly, as we move a positive test charge towards a point with a higher electric potential, it gains electric potential energy.

**Work Done:**

The work done on a charge moving in an electric field is given by the equation:

W = q * V

where W is the work done, q is the magnitude of the charge, and V is the electric potential.

If we have a test charge of 1 coulomb (C) and the electric potential at a point is 1 volt (V), then the work done to move the test charge to that point would be:

W = (1 C) * (1 V) = 1 J (joule)

This means that 1 joule of work is done to move the test charge of 1 coulomb from infinity to the point with an electric potential of 1 volt.

**Significance of 1 Volt:**

The volt is the unit of electric potential in the International System of Units (SI). It is a scalar quantity that provides a measure of the electric potential at a specific point in an electric field. By specifying the electric potential as 1 volt, we establish a reference point for measuring potential differences and understanding the behavior of charges in an electric field.

In practical terms, 1 volt represents the potential difference between two points in a circuit when 1 joule of work is done to move 1 coulomb of charge between those points. It is a fundamental unit used in calculations and measurements related to electrical circuits, devices, and systems.

In conclusion, when we say the electric potential at a point is 1 volt, it means that 1 joule of work is done to move a positive test charge of 1 coulomb from infinity to that point. The volt serves as a reference for measuring potential differences and plays a crucial role in understanding and analyzing the behavior of charges in electric fields.

One volt is the potential difference between two points in a current carrying conductor when 1 joule of work is done to move charge of 1 coulomb from one point to the other.
1 volt=1joule/1 coulomb.
