Electronics 2

Course Code ECME-124
Lecture hours per week 2
Lab hours per week 2
Course Availability: Open

Electronics 2 is planned to advance the apprentices understanding of electronics in the electrical trades. Many machines, motors, and drives are DC or controlled by DC.

Electricians today have to troubleshoot and repair these complex systems. AC drives and DC drives are more complicated with major electronic devices switching or controlling many amps and volts. To become a more competent electrician of the future, an apprentice needs to understand electronics systems and devices used in monitoring and control of electrical systems.

In this course we will review the use of an oscilloscope to test circuits; explain the importance of isolation, when using test equipment; describe and demonstrate half and full wave rectification; connect capacitors and inductors to filter a power supply output; demonstrate the use of a Zener diode as a regulator; demonstrate the operation of an SCR, DIAC and TRIAC; demonstrate how a DIAC and RC network can be used to phase shift a TRIAC; describe the operation and applications of a pulse transformer; explain the operation of a field effect transistor (FET) and operational amp (Op Amp ); calculate the expected gain of inverting and non-inverting Op-Amp circuits; and demonstrate the operation of an Op-Amp used as a comparator and an amplifier.
