The potential difference between points ...

The potential difference between points A and B in the circuit shown in fig. 5.317 is 16V. Then

A

the current through the `2Omega` resistance is 3.5A

B

the current through `4Omega` resistance is 2.5A

C

the current through `3Omega` resistance is 1.5A

D

the potential difference between the terminals of the 9V battery is 7V

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
For loop CEFD, `-2(I - I_(1)) +1I_(1) + 9 = 0`
`or 3I_(1) - 2I = -9`

From A to B via CD, `V_(A) - 4I - 9+3 - 1I_(1) - 3I = V_(B)`
But `V_(A) - V_(B) =16V, so 8I + I_(1) = 10`
or `I_(1) = -2A, I = 1.5A`
or `I-I_(1) = 1.5 +2=3.5A`
`V_(C )- 9 - 1I_(1) = V_(D) or V_(C ) - V_(D) = 7V`
