Before you begin the lab simulation, answer the first two questions. No 'cheating'! Try to answer based off your understanding of the reading. Include the Ohm's Law equation in your answers and be specific.

As you change the value of the battery voltage, what does this do to magnitude of the current through the circuit and to the resistance of the resistor?

As you change the value of the resistance of the resistor, what does this do to the current through the circuit and the battery voltage

Now, visit the PhET Ohm's Law Simulation and begin an experiment.

Select a value of resistance. Now, increase the potential across the resistor. How does the current change? How does this match what you predicted above? Be specific about what you did and what you observed.

Select a value of potential. Now, increase the resistance. How does the current change? How does this match what you predicted above?

Complete the table:

Voltage	Current	Resistance
0.5V		600 Ohms
1.0V
2.0V
3.0V
4.5V
6.0V
8.0V
0.5V		300 Ohms
1.0V
2.0V
3.0V
4.5V
6.0V
8.0V
0.5V		60 Ohms
1.0V
2.0V
3.0V

8.0V

Graph your data. Plot the voltage V as the independent variable on the X-axis and the current Ias the dependent fariable on the Y-axis. Insert a screenshot of your graph.

Here is a video showing how to make the graph using Excel. https://www.youtube.com/watch?v=gBbGBrHTMrM You have Excel via the Office 365 widget on the right side of the course homepage, so be sure to use it to make this graph.

What kind of relationship did you obtain? Directly proportional? Inversely proportional? What can be concluded from the relationship? How are voltage and current related?

An application of Ohm's Law is an electric motor. Find a resource on how electric motors work.

One of the best ways to test your understanding of the concepts you learn is to explain those concepts to someone else. To do this you will make a brief recording explaining ow an electric motor works.

IMPORTANT NOTE: Just like with written work, it is possible and easy to plagiarize in an oral form.Be careful here. The goal of this question is NOT to have you read from some web site about electric motors. You may look up information but be sure to provide the explanation in your own words. Consider making some notes or a brief outline for your recording, but avoid writing out a full script, since that is where the tendency to plagiarize occurs.
