The potential difference `(V_(A) - V_(B))` between the points A and B in the given figure is

A

`+ 6 V `

B

`+ 9 V`

C

`- 3 V`

D

`+ 3V `

Text Solution

Verified by Experts

The correct Answer is:
B
`+ 9 V`
According to Kirchhoff.s rule, by going from A to B,
`V_(A) - 2(2) - (3) - (2) (1) = V_(B)`
`therefore V_(A) - V_(B) = 4 + 3 + 2 `
`therefore V_(A) - V_(B) = 9 V `
