There are four different circuits with bulbs(identical) and batteries as shown here .

In which circuit will the bulb (s) be the brightest ?

A

Circuit P

B

Circuit Q

C

Circuit R

D

Circuit S

Text Solution

Verified by Experts

The correct Answer is:
C
The number of cells in circuits P and R is greater than in circuits Q and S . There are two bulbs in the circuit P but one bulb in the circuit R . Hence , the bulb will be brightest in circuit R .
