Geocache Description:

Solve a few simple voltage drop challenges to help you find a cache and win a mystery smiley!

Resistors are arguably the most common electronic device. They're so prevalent most of us use them daily.

The resistor's primary job is to limit the amount of current that flows through a circuit. Ohm is the unit used to express how much resistance a resistor provides.  The uppercase Greek letter Omega represents this unit.

I call your attention to the colorful bands on the resistors in the image above. They have a special meaning based on color and position.  I'll share a handy color-chart that should prove useful in determining a given resistor value. You'll use the chart to help you solve the six challenges of this fun, educational, puzzle cache.

For this string of fun challenges you may find the Ohm's Law Formula wheel I share below helpful.

 

 

 

Solve for Position X - Calculate the voltages on the DMMs

 

For this challenge you'll need to:

Caculate voltage drops displayed on the digital multi-meters

Identify the highest and lowest voltages

Subtract the lowest voltage from the highest

Round the calculation above to the nearest whole number 

 

 

Cache 6 - Position X

 

 

Solve for Position Y - Calculate the voltage displayed on the DMM

Round the value to the nearest whole number

 

Cache 6 - Position Y

 

 

Solve for Position Z - Calculate the voltage displayed on the DMM

 

To get the value for you seek you'll need to do the following: Calculate what you believe will be displayed on the DMM. Round your calculation to the nearest whole number. Let's call that value ALPHA. The solution for Position Z = ALPHA minus Position Y

 

Cache 6 - Position Z

 

 

Solve for Position I - Calculate the voltage on the DMM

 

Calculate the value and round to the nearest whole number.

 

Cache 6 - Position I

 

 

 

Solve for Position J - Calculate the voltages on the DMMs

 

Calculate the values you believe will be displayed on the DMMs

Add the values 

Round to the nearest whole number.

 

Cache 6 - Position J

Solve for Position K - Calculate the voltage on the DMM

 

Round the value to the nearest whole number

 

Cache 6 - Position K

  

  

  

Cache 6 - Checksum

 

 

 



I placed an 'easter egg' in the gallery for cachers interested in such things.
