I would like to have a formula, to calculate the resistance ratio of a log pot, depending upon its wiper posistion.

Example: the wiper of a 10K log pot is at it's midway position (50%), what is then the calculated value at that point. I know a linear pot is at 50% position 50/100xRt, but how do I do this with a logarithmic pot?

Your help will be very much appreciated.

tnx Flyer.
