## Texts and Materials

Boylestad Introductory Circuit Analysis 11th edition

## Course Activities and Design

Lecture, discussion, online lessons, and in class and lab exercises are the instructional methods used.

Laboratory activity includes building, analyzing, and troubleshooting DC circuits on solderless protoboards and industrial trainers. Instrumentation will be used to measure resistance, voltage, and current. Theoretical predictions will be compared with observed values. Computer applications will be used to process lab data, write lab reports, and simulate circuits.
