Transcript Predict and Explain Task - Adding a Resistor in Series

Add a Resistor in Series
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.
Consider the following circuit. An
additional resistor will be added in
series. Answer the following
questions.
What will happen to the reading on
the ammeter?
It will increase
B. It will decrease
C. It will remain the same
D. Some other answer
A.
What was your reason?
The resistance went up so less current
B. More light bulbs so more current
C. The battery remains the same so no
change
D. Some other answer
A.
What will happen to the brightness of
each light bulb when the third one is
added?
It will remain the same.
B. It will increase
C. It will decrease
D. Some other answer
A.
