Resistor Networks
Part 1: Selecting Resistors
You are given 5 different resistor values in the following table. If each one has a power rating of
125mW, what is the maximum voltage that can be applied across each resistor without exceeding its
power rating? No need to build any circuits for this question.
Resistor Value (Ohms) Maximum Voltage
5 0.791V
50 2.5V
5k 25V
100k 111.803 V
1M 353.553V
Part 2: Power Supplies
Hardware: Build the circuit shown using a DC power supply and a 1k resistor. For each Voltage
setting of V1, measure and record the current through the resistor (passing in the clockwise direction).
Include a photo of your built circuit (breadboard and components) here:
1
, Voltage (V1) Current Through R1
1V 0.997mA
2V 1.99mA
3V 2.991mA
4V 3.988mA
5V 4.985mA
Plot the Voltage vs. the Current. Use MATLAB,
excel, any other software, or plot by hand to-scale What is the slope of the plot?
on a piece of paper and include here a photo of your ___1000.07_______A/V
plot. Don’t forget the units on your plot on both
axes.
What is the theoretical value of the slope?
1000V/A
