ELEC 101, Spring 2005
Prof. Rich Kozick
Laboratory 1
Basic Electrical Quantities and Measuring Voltage
This lab session provides an introduction to
three fundamental electrical quantities:
charge, current, and voltage.
We will also learn how to measure voltages with the
multimeter and the oscilloscope.
We will use
an interactive computer program
(and electronic lesson or E-lesson)
developed by Professor
Mastascusa so that you can explore these
topics at your own pace.
You are encouraged to revisit the E-lessons throughout this course!
Start the E-lesson Exploring Electrical Engineering
by clicking the link below.
http://www.facstaff.bucknell.edu/mastascu/eLessonsHTML/EEIndex.html
Or, you can get to the E-lesson as follows.
- On the Bucknell web site, do a People Search for
mastascusa.
- Click on Professor Mastascusa's Web Page.
- Scroll to the bottom of the page, and click on
Basic EE Lessons.
Please perform the following activities.
- Under the menu item Basic Concepts,
go through the lessons on
Charge, Current, and Voltage.
Please do some of the exercises given in the lessons - you don't
have to do them all now.
Before moving on to item 2, provide brief explanations to the
lab instructor for charge, current, and voltage.
That is, be sure to understand the meaning of each of these fundamental
quantities are before moving on!
You will also read about charge, current, and voltage in Chapter 1
of the text.
In your lab notebook, explain charge, current, and voltage in your own
words.
- Do the lesson on Measuring Voltages.
Get there by going back to Basic Concepts, and then go
to the Measurements topic.
This lesson
will teach you how to use the
digital multimeter (DMM) to make voltage and other measurements, and
it will also teach you how to use the oscilloscope.
Note you will have to click to the lesson on measuring
voltage.
Omit any exercises using the A/D board.
Use the DMM to measure a voltage from the power supply, and
use the oscilloscope to measure a sinusoidal voltage produced
by the function generator.
Make some notes in your lab notebook about how to use these instruments.
- Feel free to browse other E-lessons in the
Exploring Electrical Engineering tutorial
to get an idea which topics are included.
However, you do not have to do any other lessons for this week.
- You are free to use the EE laboratory at any time
to work on lab projects.
The combination to the door lock will be given to you during the
lab session.
The same combination works on the other EE labs (Dana 303 and 305).
Thank you, and have fun!
