Transcribed Image Text:Use the information and dagrams below to answer the following question.
Students in a Physics classroom were given a battery, switch, and 2 ight bulbs.
Group 1 builds the series circuit as shown below and Group 2 builds the parallel
circuits as shown below. Both groups observe the brightness of the bulbs.
Series Circult
Parallel Circult
Observation1
The brightness of bulbs in both groups' circuits would be
the same since the current is the same in both circults.
Observation 2
The brightness of bulbs in Group I's circuit would be
brighter than in Group 2's circult since the total current in
series is grenter than in parallel,
Observation 3
The brightness of bulbs in Group 1's circuit would be
dimmer than in Group 2's circult since the total current in
series is smaller than in parallel.
Observation 4
The brightness of bulbs in both groups" circuits would be
the same since the voltage is the same in both circuits.
Which one of the observations below is correct?

Expert Solution
Step 1 Explanation
From the given experiment we conclude that there are two possible circuits that are
1. Series circuit
2. Parallel circuits
In series, circuit bulbs are placed series in the circuit such results the voltage is divided in to across the bulb but the current is the same
In a parallel circuit, bulbs are placed parallel in the circuit such result the current split across the bulbs but the voltage is same
