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!
-
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.
(1A = .001mA = .000001uA)
Figure 1.
-
Voltage and current measurements.
-
Using a multimeter, measure the actual resistance of the 10K ohm resistor
(before
building the circuit).
-
Build the circuit in Figure 1 on the protoboard. With the multimeter set
to measure DC volts, measure the voltage across the resistor.
-
Using the data you collected from 2a and 2b, calculate the current, I,
through the resistor. Express your answer in milliamps.
-
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.

-
"Break" your circuit, and insert the multimeter into it to complete the
connection.. Measure I using the multimeter. Write your answer here.
-
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.
-
Safely boot a lab PC from Linux mode to Windows NT mode. Have a lab TA
initial here. ______
-
Safely boot a lab PC from Windows NT mode to Linux mode. Have a lab TA
initial here. ______
-
Successfully log on under the Windows NT operating system._____
-
If you have not done so already, change your password from your first default
password._____
Question:
-
What reasons can you think of that may explain why your experimental values
for I were different than your theoretical value?
