Q. 39
How to solve this circuit
The total resistance between x and y in ohms is :-

Answer 1

$\frac{24}{17}\Omega$

View the re-draw first:

> Since 4 (from the 4-8-4 triangle) is directly connected to both x and y, it is effectively only between them, and doesn't contribute to the other branches.

> 8 and 2 have common beginning and ending terminals - they are in parallel, and so are the 4 and 6 on the right hand side.

Using the re-draw:

C and D in parallel: effective = 1.6 ohms.

E and F in parallel: effective = 2.4 ohms.

(CD) + (EF) = 1.6 ohms + 2.4 ohms = 4 ohms.

We now have 3 branches with effective 4 ohms each.

These are in parallel => net resistance between x and y = 4/3 ohms (3).
