Worked Solution
Step 1: In a parallel circuit, each bulb receives the full voltage of the batteries.
Step 2: In a series circuit, bulbs share the voltage and have higher total resistance.
Step 3: Therefore, bulbs in parallel are brighter than those in series.
Correct answer: Setup B (2 bulbs in parallel)
