Question

what is the total resistance between A and B ?​

Answer 1

Explanation:

Resistance of AF and FE are in series. so total =2+2=4Ω

Now it is in parallel with AE(4Ω).

So, effective resistance between A and E is

4

1

=2Ω

Now it is series with ED(2Ω).So total =4Ω which in parallel with AD(4Ω).So effective between A and D is 2Ω.

Answer 2

you may go through the above solution it's alright
