In the given circuit if `I_(1)` and `I_(2)` be the current in resistance `R_(1)` and `R_(2)` respectively then:

Options

A. `I_(1) = 3 A, I_(2) = 2 A`
B. `I_(1) = 0, I_(2) = 2 A`
C. `I_(1) = 2 A, I_(2) = 2 A`
D. `I_(1) = 2 A` and `I_(2)` can’t be determined with given data

Answer

D

Explanation

(d) Since `3 A` in upper part of circuit. Therefore out of `5 A` coming in lower part, `3 A` has to go to the upper part. Out of which some part will flow through `R_(2)` and rest through the unknown resistance.
`:. 2 A` will go through `R_(1)`
