Question

Find equivalent resistance :

Answer 1

Heya!!

Start by LHS;

AF & FE are in series in parallel with AE :

Hence 1/R = 1/6 + 1/6

=) 1/R = 1/3

=) R(AE) = 3 ohms

Again AE & DE are in series in parallel with AD:

=) 1/R = 1/6 + 1/6

=) 1/R =1/3

=) R(AD) = 3 ohms

Again AD & DC are in series in parallel with AC:

=) 1/R = 1/6 + 1/6

=) 1/R = 1/3

=) R(AC) = 3 ohms

Again AC & BC are in series in parallel with AB:

=) 1/R = 1/6 + 1/3

=) 1/R = 1/2

Hence R (AB) = 2 ohms.

Hope it helps uh!!
