## Homework Statement

I got this on a quiz today - Find the equivalent resistance between E and F.

Now, the problem with this question is that I get TWO different answers when I trace from:

1. e to f

2. f to e

I know one of them is definitely wrong (or maybe both are?), but I don't know which.

## The Attempt at a Solution

Now, if I go from E to F, I get:

1. Current goes through short circuit, then splits between two paths. so

**R4//(R2+R3)**

If I go from F to E (which I've drawn in colors), I get:

2. Current splits between R3 and R4. Then following R3, it splits into R1 and R2. R4 then follows through the short circuit back to E, so

**R4//(R3+R1//R2)**

In the end I had to pick one answer so I randomly chose 2 for arbitrary reasons. But what's the way to go about this problem, and which one is correct? (IF one of them is?)
