1. Predict and Explain Task
Add a Resistor in Series

2. Several Circuits will be modified by changing the number of light bulbs. Your task will be to predict and explain how adding the light bulbs will change the reading on the ammeter and the brightness of each bulb.

3. Consider the following circuit
Consider the following circuit. An additional resistor will be added in series. Answer the following questions.

4. What will happen to the reading on the ammeter?
It will increase
It will decrease
It will remain the same
Some other answer

5. What was your reason? The resistance went up so less current
More light bulbs so more current
The battery remains the same so no change
Some other answer

6. What will happen to the brightness of each light bulb when the third one is added?
It will remain the same.
It will increase
It will decrease
Some other answer
