What you will learn in this guide

The overall aim of this guide is to introduce the basic principle and application of Electrical Energy and its association with Magnetism. Learning from this guide you will learn that an electric field is always associated with a magnetic field and vice versa.

You would see that this bond between Electricity and Magnetism is the basis of many scientific and technology developments during the last century.

Towards the end of the guide you will be introduced into some aspects of Modern Physics where we have introduced some new concepts to explain sub-atomic phenomena! These include quantum theory, and energy levels in atoms.

The aim of this guide can be summarized as follows – This guide aims to give you an understanding of Electricity, Magnetism and Modern Physics and their applications in everyday life.

This will be achieved by:

  • Introducing you to the fundamentals of Electricity, Magnetism and Modern Physics as subjects on their own right.
  • Demonstrating how the various theories can be applied to real life situations.
  • Explaining some fundamental concepts in Electricity, Magnetism and Modern Physics.
  • Explaining the transition from Newtonian Mechanics to Quantum Mechanics.
  • Giving you some insight into possible future development in these areas
The number of the lines of force crossing any surface depends on three factors – the field strength, E, the surface area, S and the orientation of the surface relative to the electric field.

In addition, each unit also has specific objectives. The unit objectives are always included at the beginning of a unit; you should read then before you start working through the unit. You may want to refer to them during your study of the Unit to check your progress.

You should always look at the Unit objectives after completing a unit. In this way you can be sure that you have done what was required of you for the unit!

Set out below are the objectives of the guide as a whole. By meeting these objectives you should have achieved the aims of the Course as a whole.

On successful completion of the this guide/course, you should be able to:

  1. Describe the theory of electricity, magnetism and electromagnetic radiation
  2. Explain the concepts of electric and magnetic fields
  3. Measure and compute electric current in DC circuit and AC circuit
  4. Illustrate the principles of electromagnetic induction as they apply to both d.c. and a.c. generators
  5. Demonstrate how circuit elements are connected
  6. Describe the principles of cathode ray oscilloscope, ammeters, voltmeters, x-ray tubes and dry cells as well as accumulators
  7. Identifying the advantages and disadvantages of x-rays
  8. Describe the structure of the nuclear atom
  9. Distinguish between geographic and geomagnetic meridians
  10. Describe the terrestrial magnetic field
  11. Distinguish between nuclear fusion and nuclear fission
  12. Describe the generation and distribution of electric power
