"Offered" lists sections in this catalog year's class schedules: Summer 2026.

### ETEC 110 — DC Circuits

- **Units:** 3
- **Hours:** 66 contact hours total
- **Transfers to:** CSU
- **Offered:** not on the Summer 2026 schedule

This course is an in-depth study of Direct Current (DC) electronic circuits. Students will learn how to interpret and create electrical schematics. Other topics include Ohm's Law, Kirchhoff's Laws, resistance, capacitance, and inductance. Lab activities will include the use of multimeters, power supplies, and oscilloscopes; building and analyzing common DC Circuits; and validating theoretical calculations by testing circuit performance.

### ETEC 120 — AC Circuits

- **Units:** 3
- **Hours:** 66 contact hours total
- **Transfers to:** CSU
- **Offered:** not on the Summer 2026 schedule

This course is an in-depth study of Alternating Current (AC) electrical circuits. This course focuses on the math describing AC circuits, specifically the relationships between impedance, resistance, and reactance. Students will use these concepts to anticipate power factors and learn how to mitigate large inductive loads. Students will design, analyze, build, and test resistance/conductance/capacitance (RLC) circuits, inductance motor drivers, and filter circuits for audio signals. Lab work will include validating theoretical calculations by building circuits and testing them for expected performance.

### ETEC 130 — Programmable Logic Controllers

- **Units:** 3
- **Hours:** 66 contact hours total
- **Advisory:** Completion of any mathematics course at the Intermediate Algebra level or above with a grade of "C" or better.
- **Transfers to:** CSU
- **Offered:** not on the Summer 2026 schedule

Students will learn how to connect Programmable Logic Controllers (PLCs), upload and backup programs, and obtain diagnostic data from operational PLCs. Students will interpret and draw ladder logic diagrams, and document and implement control processes using ladder logic programming on PLCs. Lab activities will include connecting various process sensors to PLC inputs as well as connecting relays to outputs to drive motor contactors, indicators, and handshaking.
