Course code: BEC021
Duration: 1 months (4 weeks)
This is beginners course in basic electronics, the course is composed of 15 lessons covering all common electronics components (both
passive and active) found in consumer electronics equipment like LCD television
and Monitors, CRT television and Monitors, DVDs, Hi-fi systems, Power
amplifiers, Switch mode power supplies (S.M.P.S) etc.
In this course you will learn how to identify various
components using actual picture, symbol used to represent them on the circuit
board, purposes it serves on the circuit, common failure modes and how to test
if it is good or bad.
The course will be done by correspondence via email,
in total there are 8 assignments, if you decide to do two assignment per week
means you will take only 4 weeks (1 months) to complete the course. All assignments
will be in MS Word format.
You will read the course material and complete your assignment then return it
via email to your facilitator/trainer. The facilitator will then review your
assignment and give you feedback on your work.
You can progress at any pace, fast or slow. Your assignment will then be returned to you via email with your next assignment.
Upon completion of this course you will have a solid foundation in electronics to get you started in this exciting career in electronic repair like LCD-LED television repair, microwave repair, home theater repairs, woofer repair, decoders, amplifiers among others.
