1.

The entire network shown here, has uniform wire having resistance per unit length as 1Omega//m. It is placed in a uniform but time varying magnetic field vecB(directed into the plane). If the strength of the magnetic field is increasing at 1T//s, the ratio I_(1)//I_(2) equals

Answer»

`2`
`4`
`1//3`
`1//6`

Solution :`3(I_(1)+I_(2))+I_(1)=1`
`RARR 4I_(1)+3I_(2)=1`…..(`i`)
`2I_(2)-I_(1)=1//2`
`rArr-2I_(1)+4I_(2)=I`……(`ii`)
By solving equations (`i`) and (`ii`)
`(I_(1))/(I_(2))=(1)/(6)`
