How to get credit for this activity

First, sign-in at the computer and sign-out when the activity is complete. Show your work and results to a PLC tutor so they can check your work and initial the signoff sheet. Be prepared to answer questions about the activity or your results.

Get five 10k Ω resistors, a circuit board and a Digital Multimeter (DMM). a. Measure and record the individual resistance of all 10k Ω resistors using a DMM. b. Draw diagrams showing how you could arrange 3 of these 5 resistors so that their equivalent theoretical resistance is

Three resistors in series

Three resistors in parallel

One resistor in series with two in parallel

One resistor in parallel with two in series c. Using a DMM, measure the equivalent resistance and compare the predicted and measured values using a percent difference. How do they compare? d. Using two additional 10k Ω resistors predict and measure the equivalent resistance

R eq

of the following circuit. How do they compare?
