There are 4 lessons in this physics tutorial covering Electric Potential Difference (Voltage). Ohm's Law. The tutorial starts with an introduction to Electric Potential Difference (Voltage). Ohm's Law 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 Difference (Voltage). Ohm's Law. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

  • What is the scientific definition of electric potential?
  • Why potential difference is more important that the electric potential itself?
  • Why the potential difference produced by a battery is different from the potential difference produced by a charged object?
  • What is the electromotive force?
  • What are the common things and the differences between electromotive force and potential difference as concepts?
  • What does Ohm's Law for a part of a circuit say?
  • What is the general form of Ohm's Law for the whole circuit?

Introduction

Do you think the amount of extra charges available at any part of a circuit is enough to produce a sustainable electricity in a circuit? Why? What else do you think is necessary for this?

Is there any kind of relationship between the current flowing through a circuit and the resistance provided by the operating devices in that circuit?

What parameters are stamped on the back plate of an electric appliance? Do you know their meaning?

In this tutorial, we will elaborate further the explanation of the potential difference concept discussed in the previous section. In addition, we will relate this concept to other quantities involved in the study of an electric circuit. Therefore, we consider this tutorial very useful in the practical aspect.
