EE 101 Introductory Lab Exercise

This exercise does not have to be completed in a comp book, but starting with the next lab, a comp book must be used.

 Part I. Voltage and Current Measurements. SHOW ALL UNITS WHERE APPLICABLE!

  1. Before building the circuit, using Ohm's Law, calculate the current through the 10K ohm  resistor. Give your answer in amps (A), milliamps (mA), and microamps (uA). Show your work to the right of Figure 1.  (1 mA = .001A, 1uA = .000001A)



    2. Figure 1.

  2. Voltage and current measurements.
    1. Using a multimeter, measure the actual resistance of the 10K ohm resistor (before building the circuit).
    2. Build the circuit in Figure 1 on the protoboard. With the multimeter set to measure DC volts, measure the voltage across the resistor.
    3. Using the data you collected from 2a and 2b, calculate the current, I, through the resistor. Express your answer in milliamps.
    4. Calculate the percent difference between the value for I you obtained in 2c, and the theoretical value for I you calculated in problem 1. Write your answer here.


    5. "Break" your circuit, and insert the multimeter into it to complete the connection.. Measure I using the multimeter. Write your answer here.
    6. Calculate the percent difference between the value for I you obtained in 2e and the theoretical value for I you calculated in problem 1.
Part II. Booting the lab PC's safely.
  1. Safely boot a lab PC from Linux mode to Windows NT mode. Have a lab TA initial here. ______
  2. Safely boot a lab PC from Windows NT mode to Linux mode. Have a lab TA initial here. ______
  3. Successfully log on and off under the Windows NT operating system.______
Question:
 
 
  1. What reasons can you think of that may explain why your experimental values for I were different than your theoretical value?
