# Physics Tutorial 14.5 - Electric Potential

There are 8 lessons in this physics tutorial covering Electric Potential. The tutorial starts with an introduction to Electric Potential and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Electric Potential. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

• What is electric potential (definition, formula, unit)
• What is potential difference? How is it related to the work done by the electric force?
• What are the similarities between gravitational and electric potential and potential energy?
• What are equipotential surfaces? What is the potential difference in any two points of equipotential surfaces?
• What is the common potential of a number of charged objects connected with each other through conducting wires?
• How to calculate the electric potential of a charged sphere? How does it change in different positions?
• How to deal with motion caused on a charge when it is inserted inside a uniform electric field?

## Introduction

In the previous tutorial, we have explained the concept of electric potential energy. Does it depend on the amount of test charge Q0 placed inside the electric field produced by the charge Q?

Is it possible to identify any quantity that does not depend on the amount of test charge, but which can represent quantitatively the electric field properties?

In this tutorial, we focus precisely on this i.e. in dealing with a specific quantity representing the electric field, which is independent on the external factors such as the test charge. This quantity is known as electric potential.
