The potential difference between A and B...

The potential difference between A and B as shown in figure is

A

1V

B

2V

C

3V

D

4V

Text Solution

Verified by Experts

The correct Answer is:
A
Resistance of the upper arm `CAD=2Omega+3Omega=5Omega`
Resistance of the lower arm `CBD=3Omega+2Omega=5Omega`
As the resistance of both arm are equal, therefore same amount of current flows in both the arms. Current through each arm. CAD or CBD=1A
Potential difference across C and A is `V_(C)-V_(A)=(2Omega)(1A)=2V...(i)`
Potential difference across C and B is `V_(C)-V_(B)=(3Omega)(1A)=3V...(ii)`
Substracting (i) from (ii), we get
`V_(A)-V_(B)=3V-2V=1V`
