I WILL GIVE BRAINLIEST :) Part 1: Answer the following questions (20 points)
1. Name and describe the components needed to make a complete circuit.
2. Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different.
3. Ohm's law is represented by the equation I = V/R. Explain how the current would change if the amount of resistance decreased and the voltage stayed the same.
4. Define resistance and describe what would happen to a light bulb if the voltage increased but the resistance stayed the same.
Part 2: Design your own circuit (40 points)
Design a circuit and draw a circuit diagram using the proper symbols. Your circuit must contain a battery, a light bulb (if you would like to substitute another item that uses electrical power you may), a switch, an ammeter, and a resistor. After you draw your circuit, complete the questions which ask you to describe the circuit that you have created. You may hand draw the circuit and scan or fax the worksheet to submit for grading. Or you may use a draw/paint program to create your circuit in the space provided.
You will be awarded points as follows:
Circuit contains all required parts – 5 parts (1 point each) 5 points
Circuit is properly constructed and would work 5 points
Symbols are correct and properly placed – 5 total (1 point each) 5 points
Question 1 explanation 5 points
Question 2 explanation 5 points
Question 3 explanation 5 points
Question 4 explanation 5 points
Question 5 explanation 5 points
Total point value 40 points

Circuit Diagram:

Question 1: Is the circuit you created a parallel, series or a series/parallel circuit? Support your answer with a description of this type of circuit.

Question 2: What is the purpose of the resistor in your circuit?

Question 3: How does the switch work?

Question 4: Describe the path of the electric current through your circuit.

Question 5: Explain how your battery works. (You may want to look at the Electric Current lesson) What are some possible materials you could use to make your battery?
