How ELECTRICITY works
This video is a summary of the Electricity notes we will discuss in class. It is a great idea to watch it again after class in order to make connections to our discussion.
Electricity and Magnetism Notes
Ohm's Law
Use this phET simulation to manipulate the different variable of Ohm's law. Ohm's law states that voltage(V) is equal to the current(I) multiplied by the resistance(R).
Answer the following questions.
What happens to the current as you increase or decrease the voltage?
What happens to the current as you increase or decrease the resistance?
Explain the relationship of all three variables and describe whether their relationship is proportional or inversely proportional.

Series vs. Parallel Circuit Videos
Watch the following videos to get a better understanding of series and parallel circuits. You can stop watching the first video after 4:10 minutes. You do not need to know how to calculate Ohm's law for combination circuits.
Watch this next video all the way through.
Circuit Construction Kit- Virtual Lab
Use the following phET lab to complete the activity in your packet. After completing the lab, you will need to compare and contrast advantages and disadvantages of series & parallel circuits.
What is an Electromagnet?
Watch this quick doodle video to see how an electromagnet works and to understand electromagnetic induction used in a generator.
How electric motors work...
Watch the following video to see some examples of electric motors used in everyday devices. It will also break down the process of how electric motors convert electrical energy into mechanical using an electromagnet.
Electromagnetic Induction
Place the magnet inside the coil of wire. What happens to the light in the light bulb? How could you get the light to continue to stay lit?
Now click on the sim to view the screen with two sets of coils. What is the difference in the amount of light produced by the different groups of coils? How does this relate to a transformer? Which set of coils would be primary and secondary if you were creating a step-up transformer? What about a step-down transformer?
