    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.

    Thanks in advance!

    That is a circuit?
