Question

Rizvi has connected two bulbs across two cells in a simple circuit. How can he make the bulbs dimmer?

• A. Replace one of the cells with a cork
• B. Replace one of the cells with a wire
• C. Replace one of the bulbs with a cork
• D. Replace one of the bulbs with a wire

Answer 1

The correct option is B Replace one of the cells with a wire

Using a cork in the circuit will break it, since it is an insulator. Removing one of the cells will reduce the flow of electricity and make the bulbs dimmer.
