In the given circuit the potential at point B is zero, the potential at points A and D will be

A

`V_(A)=4V, V_(D)=9V`

B

`V_(A)=3V, V_(D)=4V`

C

`V_(A)=9V, V_(D)=3V`

D

`V_(A)=4V, V_(D)=3V`

Text Solution

Verified by Experts

The correct Answer is:
D
`V_(A)-V_(B)=2xx2=4V`
`thereforeV_(A)-0=4VRightarrow V_(A)=4V`
According to the question `V_(B)=0`
Point D is connected to positive terminal of battery of emf 3V.
