Course Description

Covers basic alternating current (AC) concepts and theorems to analyze AC circuits. Analyzes basic circuits in practical applications. Prerequisites: EET 112. Audit available.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Analyze alternating current (AC) power and transformers.
  • Analyze resonant circuits and filters.
  • Analyze three phase power distribution.
  • Perform calculations with pulse waveforms.

Course Activities and Design

Lecture and discussion are the instructional methods used. Weekly homework is assigned. Laboratory activity includes building circuits on solder-less breadboards, making circuit measurements using test equipment, analyzing test data, and comparing to predictions using theory.

Lab exercises involve using a PC with spreadsheet, word processor, and circuit simulation software. The student is expected to learn the following in the lab:

Use the DMM (digital multi-meter) to measure AC voltage, and current.

Use the Oscilloscope to measure AC waveforms in the time domain.

Use the oscilloscope to measure phase angles between two AC waveforms.

Use the function generator to generate waveforms at specific frequencies and amplitudes.

Build circuits on a solder-less breadboard.

Use the DC power supply

Use the spreadsheet and word processor to process lab data and to write lab reports.

Use circuit simulation software to simulate circuits built in the lab.

Outcome Assessment Strategies

Evaluation is by exams, homework, and lab work.
