1. Start the program Exploring Electrical Engineering on the PC at your lab bench. A shortcut to the program is available in the Favorite Programs folder.

2. Under the menu items Basic Concepts and Quantities, go through the lessons on Charge, Current, and Voltage. Please do the exercises given in the lessons. Feel free to ask the instructor if you have any questions.

   You will also read about charge, current, and voltage in Chapter 1 of the text, and we will discuss them in class on Friday. You do not have to record anything in your lab notebooks for this part.

3. Do the lesson on Measuring Voltages, which will teach you how to use the Fluke Hydra data acquisition unit (DAU). We will use the DAU to make voltage and other measurements throughout this course. The lesson also explains the wiring of your protoboard. You do not have to do any of the exercises with resistors this week.

   Please measure the voltage differences between the various wires on the power supply in your lab kit. Determine which wires correspond to +12 V, -12 V, +5 V, and Ground. Record the results in your lab notebook for future reference.

4. Feel free to browse other lessons in the Exploring Electrical Engineering tutorial. However, you do not have to do any other lessons for this week.

5. You are free to use the EE laboratory at any time to run the Exploring Electrical Engineering tutorial or to work on lab projects. The combination to the door lock will be given to you during the lab session.

Thank you, and have fun!
