Question

Nidhi has two bulbs connected across two cells in a
simple circuit as shown. How can she make the
bulbs glow dimmer?​

Answer 1

Answer:

hey..

Your Answer is here..

Replacing one cell with a piece of wire reduces the current in the circuit. Hence, the bulbs glow dimmer.

Answer 2

Answer: Nidhi can make the two bulbs glow dimmer by either connecting the two bulbs in series connection or else by connecting the cells in parallel connection.

1. If she connects two bulb in series connection, the voltage received by the bulbs will get divided and hence the bulb will become dim.

2. If she connects the two cells in parallel, the total voltage received will become less than if they are placed in series connection which will further reduce the brightness of bulb.

3. If she connects the bulb in series as well as the cells in parallel, the brightness will decrease more.

Therefore using these methods she can make the bulb glow dimmer.
