Part 1: Answer the following questions (20 points)
1. Name and describe the components needed to make a complete circuit. (HINT: there are
5 parts. List all 5 parts then define them.
1.
2.
3.
4.
5.
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.
They are alike because they both
They are different because
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. (HINT: try
plugging numbers into the equation for R, but make sure V stays the same. Then
describe what happens to I(current) Click HERE to view a video that will help you.
4. Define resistance and describe what would happen to a light bulb if the voltage
increased but the resistance stayed the same. (HINT: look back in the lesson under the
section Title “Resistance”)
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)
Circuit is properly constructed and would work
Symbols are correct and properly placed – 5 total (1 point each)

Circuit Diagram: Insert your drawing of a circuit
here. This is worth 15 points!
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? (HINT: look at your answer to
question 4 above)
Question 3: How does the switch work? (HINT: look back in the lesson to find the purpose of a
switch)
Question 4: Describe the path of the electric current through your circuit.
Question 5: Explain how your battery works. (HINT: You may want to look at lesson 3.02)
What are some possible materials you could use to make your battery? DON’T FORGET
TO include information about why it is important to use two different types of materials to make
a battery. Also don't forget to discuss the electron affinities.
