Objectives: The learner will...
...apply technology tools for problem-solving in content learning. (NETS 4, 5)
... investigate and apply simulations in real-world situations. (NETS 3, 5, 6)
...solve 9 series, parallel. and combination resistance problems
 


Purpose:
Many new electronic circuits are designed and tested with special simulation software before construction of the first prototype. Using a powerful electronic lab simulator called CircuitMaker you will assemble, test and solve 9 series, parallel. and combination resistance problems!

Setup:

  1. Start CircuitMaker on a class computer or download it at home to your PC. It should look similar to the image below (without the schematic).
  2. To place a Resistance Meter on the field select Devices then Browse and choose General under Major Device Class, then Instruments under Minor Device Class and double-click Multimeter under Device Symbol. The Multimeter panel will open giving you more options. Select Ohms (for resistance) and OK.
  3. Next you will need to ground the resistance meter. The shortcut for this component is simply the 0 (zero) key. Press "0" and the ground symbol (downward pointing arrow) will appear. Place it near the right of the meter.
  4. Wire the ground to the negative (-) post of the meter by activating the wiring function with the Wire Tool Button [ + ] on the toolbar. Your resistors will be wired together and to the meter using this same function.
  5. To add resistors you will use the hotkey "r" (lowercase). When you place the resistors their default value will be 1000 Ohms (1k). To change their value just double-click on the placed resistor and enter a new value!



Procedure:

  1. Calculate the Total Resistance (Rt) using a calculator and the series, parallel & combo equations from the unit tutorial
  2. Assemble and check each of the 9 resistance circuits with the CircuitMaker program
  3. To activate the Resistance Meter once the circuit is assembled and ready for testing just click the RUN-STOP button on the toolbar (shows a picture of a person "running")
  4. Don't forget that "r" will create resistors and double-clicking them will allow you to change their values
  5. The lightning bolt button will allow you to delete any mistakenly placed parts

Conclusion:
Demonstrate to the teacher how to construct and run from scratch any of the 9 circuits above (teacher's choice). Update your website with the details of this lab experience including a short descriptive summary, calculations, and answers! The instructor will grade this lab web entry according to this rubric.
