Question

what will be the resistance between a and b ​

Answer 1

Answer:

hello dear where is your questions

Answer 2

Explanation:

Resistance of AF and FE are in series. So total = 2+2 = 4 ohm

Now it is in parallel with AE(4 ohm).

So effective resistance between A and E is \frac{1}{1/4+1/4} = \frac{1}{2/4} =4/2=2

1/4+1/4

1

=

2/4

1

=4/2=2 ohm.

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

It goes on and finally the effective resistance between A and B is 2 ohm.
