3 bulbs are in series and the same 3 bulbs are in parallel with the same battery. Which bulbs will be dimmer? A. The same
B. Parallel
C. Series
D. Not enough info

Explanation:

The series three. The series 3 will cut the voltage into 1/3. The current will also be lower because of the voltage drop.

The parallel circuit will not cut the voltage and the current will be tripled because each bulb is taking out exactly what it needs.

As an aside, house wiring would be a nightmare if the bulbs were connected in series. If one bulb burned out, you'd have to find it in the dark because they all would go out.
