Question

Bulb connected to a series combination of three dry cells glows brighter than the same bulb when connected to a parallel combination of three similar dry cells.

• A. True
• B. False

Answer 1

The correct option is A True

When the cells are connected in parallel, the voltage of the individual cells do not add up therefore the current doesn't increase in a parallel combination. But in a series combination, the voltage of the cells add up and therefore the current from the combination increases and make the bulb glow brighter.
