Intended Outcomes for the course
1. Use basic AC concepts to analyze circuits.
2. Build and simulate AC electrical circuits and perform measurements with electronic test equipment.
3. Write technical reports using collected experiment data.
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 sinusoidal waveforms of specific frequency and amplitude.
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.
