Ulibrium is an unknown quantity at this point

Potentiometer Theory

I just want to make sure I get the basic theory correct. Inside a linear taper potentiomter, the circuit looks like this:

|--------------------- <- 5 V, I Amps
|
/
\ Unknown length X
/ Wiper
\---------------------- -> Analog Input V, I1
/ Total length Xt
\ Resistor
/ Total resistance Rt
\
|
|---------------------- -> Ground, Voltage Vg, I2
Effective Resistance R = (X/Xt) * Rt
Analog Input V = I * R
Vg = 5 - V (???)
Do I have it right so far? And if I do, does anyone know the currents I1 and I2?
