Hi guys, what I have to do is find the voltage drop of a resistor that is parallel to a potentiometer, but I'm not sure exactly how to calculate it's total resistance.

The circuit looks like this
Code ( (Unknown Language)):
1.
2.                     .5.6k
3.   -------/\/\/\----|
4. |           .      |
5. |                  |
6. ___              10K----------
7.  --  15V           |           |6.8k
8. |                  |           |
9. |__________________|___________|
10.
So, how this is connected is a 15v voltage source to a 5.6k resistor in series with a 10k potentiometer who's middle connection is directed to 5k in series with a 6.8k resistor.
My question is how would i find the total resistance given these factors?
What I'm getting as the total resistance is 641m ohms doing this:
1 / 5.6k + 10k + (1 / 5k + 6.8k)
and multiplying that to 15v gives mea total of .331 V, which i'm thinking is incorrect.

That is a circuit?
