Question

plz answer this question​

Answer 1

take total current as 6I

then if we consider the ACBA loop then

apply kkirchhoff's law of voltage

so we get 2I×R +I×R+2I×R=E

or, 5IR=E....(1)

now ,if the effective resistance between A B become r

then 6I×r=E...(2)no.

from 1no. and 2no. equation we get

5IR=6Ir

or,r /effective resistance=5R/6
