Lab Overview and Introduction

Students must attend four lab periods in total. Labs beginning with an introductory lab on "Laboratory Equipment and Measurement Methods." The next three labs cover a variety of important concepts and practical electric circuits. No matter what engineering discipline you choose, chances are that somewhere later in your studies, and certainly your engineering careers, you will encounter electric circuits in one form or another. For example, some of the simple amplifier configurations studied in Lab #3 are closely related to those employed in sensors and measuring devices in biomedical applications, and also in down-hole temperature and pressure measurements in oil and gas wells. The Wheatstone bridge, studied in past (normal) years in Lab #2, is a useful circuit configuration to sense change of resistance, such as that produced by a strain gauge in measuring stress deformation of columns and beams in civil engineering applications, or in electronic temperature measurement via thermistors. The list is practically endless!

A separate document entitled "ENGG 225 Laboratory Introduction" will posted to D2L before any lab exercises are posted. Please read this document over carefully before starting any of your lab work. It contains an overview of the lab procedures, safety tips, wiring tips, guidelines for writing up lab reports, and handy reference material such as resistor color codes. The labs are an essential part of this course.


Lab #1 - Laboratory Equipment and Measurement Methods

2021 Schedule

Section Nos. Week of
Even Feb 22 - Feb 26
Odd Feb 8 - Feb 12

The purpose of this lab is to become familiar with some of the common lab instruments, mostly just the digital multi-meter (DMM). Unfortunately, we don't have access to other instuments such an oscilloscope, signal generator, and the general-purpose laboratory breadboard.

Preparation: None for this lab.


Lab #2 - DC Resistive Circuits

2021 Schedule

Section Nos. Week of
Even Mar 8 - Mar 12
Odd Mar 1 - Mar 5

The purpose of this lab exercise is to study various resistor networks and to compare experimental observations with theoretical predictions. You will design and test a voltage divider and current divider.

Preparation: Watch for details when the lab is posted.


Lab #3 - Operational Amplifier Circuits

2021 Schedule

Section Nos. Week of
Even Mar 22 - Mar 26
Odd Mar 15 - Mar 19

The purpose of this lab exercise is to design and test various simple amplifier configurations, and to explore an application of operational amplifiers in an electronic heartbeat monitor.

Preparation: Watch for details when the lab is posted.


Lab #4 - Steady-State Sinusoidal AC Circuits

2021 Schedule

Section Nos. Week of
Even Apr 5 - Apr 9
Odd Mar 29 - Apr 2

The purpose of this lab exercise is to study AC Circuits. The following topics will be studied:

Preparation: Watch for details when the lab is posted.
