Three identical bulbs namely P, Q and R are connected to a battery as shown. What will happen when the circuit is closed?

Detailed Solution: Question 1

When the circuit is closed, an electric current starts flowing in the circuit from the positive terminal of battery. The current which passes through bulb P is the sum of current flowing in bulbs Q and R. As the brightness depends upon the current flowing through the bulb, so P will be bright but Q and R will be dim.
