Week #4: (12/3-7) Chapters 8 & 7.
Posted: Fri Nov 30, 2018 9:01 am
This week we will continue discussing Chapter 8 on Solving Electrical Problems on Monday & Wednesday and then cover Chapter 7 Solving Mechanical Problems on Friday.
Monday, 12/3:
Here are three DMM Tutorials from Wisc-online:
Introduction to the Digital Multimeter
DMM - Ohmmeter Connections
Proper Digital Multimeter Placement. (Hint: To get the probes onto the circuit test points, drag the probe until the point where the metal tip meets the plastic handle is over the connection point.)
And a couple of links on power dissipation:
Power Dissipation & Electronics Components
Power Dissipated by a Resistor
Some "Flashcards" on Significant Digits and Accuracy from Wisconline: Measurement: What is Accuracy? and Accuracy of Measurement Numbers.
How to Determine Digital Multimeter Accuracy
Accuracy & Precision Chart from Fluke. After viewing this chart, close down (Click on "X") this chart to reveal other helpful hints from Fluke.
Accuracy from National Instruments A bit mathematical, but a good presentation if you understand Algebra 1 material.
Wednesday, 12/5: The "sniff" test and using a digital multi-meter for trouble-shooting, plus finishing up any links posted from Monday.
Here's a pdf of the power dissipated by the 100 ohm resistor from the Spreadsheet: Friday, 12/7: Finish up Chapter 8 on Electrical Troubleshooting, discuss "meter loading" effects (i.e. how does using a DMM change the circuit), voltages across working & blown fuses/breakers, we'll work through a few Ohm's Law Problems and then, time permitting, begin Chapter 7 on Mechanical Troubleshooting.
Quiz Pack #3 will be distributed on Friday, 12/7. It is due on or before 10:30 am Friday, 12/14.
Some support links: You might also find it helpful to review the links posted in Week #1.
