Question

In the given circuit currents `I_1` and `I_2` are
.
A. `(10)/(7) A, (12)/(7) A`
B. `-(2)/(7)A, (12)/(5) A`
C. `(8)/(7) A, (12)/(5) A`
D. `(8)/(7) A, (12)/(7) A`

Answer 1

Correct Answer - B

`b to B :` (path BAGFB)
`V_B - I_1 xx 7 - 6 + 4 = V_B`
`I_1 = -(2)/(7) A`
`B to B:` (path BCDFB)
`V_B - I_2 xx 5 + 8 + 4 = V_B`
`I_2 = (12)/(5) A`.
