Electric potential is a fundamental concept in physics and electrical engineering, representing the amount of electric potential energy per unit charge at a specific point in an electric field. Understanding how to convert between different units of electric potential, such as volts (V) and electronvolts (eV), is essential for various applications in scientific research and practical electronics. In this guide, we will explore the electric potential converter, its importance, and how to use it effectively.
What is Electric Potential?
Electric potential, commonly measured in volts, indicates the capacity of an electric field to do work on a charged particle. It is defined as the work done to move a unit charge from a reference point (usually infinity) to a specific point in the field without any acceleration. The electric potential at a point is given by the formula:
where:
- V is the electric potential in volts,
- W is the work done in joules,
- Q is the charge in coulombs.
The electronvolt (eV) is a smaller unit of electric potential energy defined as the amount of energy gained by a single electron when accelerated through an electric potential difference of one volt. The relationship between volts and electronvolts is given as:
