Question

Pooja connects a second cell in a simple circuit, how will this effect the brightness of the bulb?

• A. It will stop glowing
• B. It will cause the bulb to fus
• C. It will become dimmer.
• D. It will become brighter

Answer 1

Answer: (D)

It will become brighter

When Pooja connects the second cell in a simple circuit, then the second cell provides additional energy to the circuit, and the bulb gets more power to glow. Subsequently the brightness of the bulb increases.

For example, a torch with a single-cell provides less light compared to a torch with double cells.
