## Homework Statement

The attached graph shows the relationship between time and voltage for three resistors. A capacitor is discharging current through three "separate" resistors. How resistors might be positioned in a circuit to give rise to the graphs.

## Homework Equations

V = IR

CR = $$\uptau$$

## The Attempt at a Solution

Separate cannot mean in parallel, or else the graphs would all begin at the same voltage.

My attempt to prove that

"Separate cannot mean completely in series either" ended in squash:

The resistance order can be shown to be: R2>R3>R1

RC = Tau gives the time constant for a capacitor. The greater tau is, the longer it takes a capacitor discharge or acquire charge. The resistors with the greater resistances, consequently, are the ones that takes the longer to reach V = 0.

What approach can I use?
