Introduction to Electronics
Pass Physics examinations and build confidence in advancing your career in Electronics
Self paced
tutorials
The course is an introduction to Electronics, a topic in Physics. Even though the course does not cover advanced electronics concepts, it does give learners a basic foundation in electronics. The course is ideal for individuals who have little or no knowledge in electronics and would want to advance their careers in the field. Since the learners will be reminded about circuits, circuit diagrams and electricity, the course is vital for those who are preparing for and want to excel in Physics examinations at high-school level. This course is not for those who would want to learn advanced electronics.
Course Package
- The course materials will be included but not limited to PPT, PDF and Doc files. The learners will be given assignments and tests at the end of each section
- The course has 2 Videos, one will be given in the middle of the course and the other at the end to aid the understanding of the project
- There are 9 PowerPoint presentations, each with a minimum of 12 slides and a maximum of 33 slides. PPT files are used in every chapter
- The number of handout PDF files is 25. However, each PDF file has a maximum of 5 pages. Even though, there is only 1 online test at the end of the course, there will be a provision of 7 assignments given at the end of chapters 1-7. These assignment will be in Doc file
Course reference material
- The learners will be provided with 3 different e-books for references. However, learners can also use online resources
- No software or material required for this course except for those willing to carry out simple project at the end of the course

David is currently pursuing M.Sc. in Statistics at Pwani University. His undergraduate programme was B.Ed Science (Math/Statistics and Physics/Electronics).
Having graduated from Kenyatta University with first-class honors in 2010, he has tutored online for two years and taught Mathematics and Physics for four years.
Although David is now narrowing down to Statistics, Electronics is one of the topics that he likes and would want to share it with others who want to advance their careers in the field.
