Answer» it can be seen that potential difference around 4+4 Ω and 1+3Ω resistance will always be same as V. so, potential in the mid of 4Ω at A will be V/2 ( both resistance are equal ) and since potential drop in the mid of 1 and 3 at B will be lesser because 1Ω is < than 3Ω , so, potential will be greater than V/2 and we know that current flows from higher to lower potential . so, here current will flow from B to A

Answer»

it can be seen that potential difference around 4+4 Ω and 1+3Ω resistance will always be same as V.

so, potential in the mid of 4Ω at A will be V/2 ( both resistance are equal )

and since potential drop in the mid of 1 and 3 at B will be lesser because 1Ω is < than 3Ω , so, potential will be greater than V/2

and we know that current flows from higher to lower potential .

so, here current will flow from B to A
