A) R will glow bright but Q and P will be dim.
B) P, Q and R all will glow equally bright.
C) Q and R will immediately burnout.
D) P will glow bright, but Q and R will be dim.
Correct Answer: D
Solution :
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 gets divided and flows 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.
