# Equivalent resistance

## Homework Statement

This problem involves a sketch of a system of resistors, so I will do my best.

A--xx1xx---|---xx1xx--B
.\..............|............./
...x............x...........x
....x...........x..........x
......3.........1........5
........x.......x.......x
..........x.....x.....x
............\...|.../
..............\.|./
................\/

The numbers between the x's represent the resistors and their vaules.

The question asks to find the equivalent resistance R[ab].

## Homework Equations

I am aware of the series/parallel relation ships between resistors, but this question seems ambiguous.

1/Req = 1/R1 + 1/R2
Req = R1 + R2

## The Attempt at a Solution

The question states that the solution should be 27/17, but anyway I work this problem I dno't seem to get this answer, although I have gotten very close.

Any help?
