Geocache Description:

This cache is not at the posted coordinates but can be found in North America.


This is my second puzzle cache in what I hope might become a long running series of puzzles on circuit theory. To find this cache, you must solve the circuit below. Since determining an exact solution will be very difficult and only possible if you carry every single digit through all of your calculations I will use Certitude. If you solve the circuit correctly you'll be close enough to get a certification and the exact solution will be provided so you can find the physical cache. Enter the certitude coordinate in the form N37 MM.MMM W121 MM.MMM



The cache is located at:
N37 42.109 + the apparent power W121 44.803 - the power factor



AC circuit

  • V0=169.705627484cos(wt) Volts
  • R1=13408.63 ohm
  • L2=26.8609 Henry



You can validate your puzzle solution with certitude.


Please be mindful of muggles while searching for this cache as they can appear suddenly without warning.
