Worked Solution
Step 1: In a series circuit, adding more bulbs increases resistance and decreases brightness.
Step 2: In a parallel circuit, each bulb receives the full voltage from the battery source.
Step 3: Therefore, bulbs in parallel shine brighter than the same number of bulbs in series.
Correct answer: Two bulbs in parallel with one battery.
