# Effective Resistance Between Points in Circuit

## Homework Statement

Four resistors are connected as shown (figure attached). Find the resistance between points a and b.

## Homework Equations

$$R_{eq} = \sum{R_{n}}$$ for series resistors

## The Attempt at a Solution

The four resistors in the figure are in series. Therefore, to determine the resistance between points a and b, we must find the effective resistance of these resistors. Summing them, we find that $$R_{eq} = 201\Omega$$. However, that answer is incorrect.

Any help in understanding this problem would be really appreciated!
