ELECTRIC CIRCUITS LABORATORY MANUAL

ELECTRIC CIRCUITS LABORATORY MANUAL (ECE-235 LAB) GUIDE LINES FOR THE EXPERIMENTS AND REPORT PREPARATION 1. Preparation for the experiment: Before conducting the experiment, the student is required to have read the experiment background and procedure from the experiment MANUAL and studied the related theory. The lab instructor may, during the experiment, ask students questions pertaining to the procedure and theory. The lab instructor may give negative points to and even prevent an unprepared student from conducting the experiment. Tardy students may not be allowed to perform the experiment.

Part 2: Resistance Measurement Background on Graphite Resistance: The standard resistor color code is shown on the back of the door to the lab. Here is a quick …
