In the circuit as shown in figure, the ratio of current `i_1//i_2` is

A

`4//3`

B

`1//2`

C

2

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
c. The circuit can be reduced as

From figure (2), `I = 6/6 = 1.0 A`
Hence, `I_2 = (I//2)/2 = I/4 = 1/4A`
`From figure (2) the current
through `4`Omega` branch
`I = (8-6)/4 = 1/2A`
Hence `I_1 = I -I = 1-1/2 = 1/2A`
or `I_1/I_2 = (1//2)/(1//4) = 1/2 xx 4/1 =2 ` .
