Question

In a circuit with one bulb, another bulb is added in series. What happens to the bulbs when current is passed?

• A. They do not glow.
• B. They glow less brightly.
• C. They glow more brightly.
• D. They get fused.

Answer 1

The correct option is B

They glow less brightly.

A circuit has one bulb, if another is connected in series, the current and the brightness of the bulbs would get reduced.Hence, the brightness of the two bulbs will be less than the brightness with which the single bulb was glowing earlier.
