Current Flows Mystery Cache

Solve a few simple branch current 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 A - Calculate the current on the DVM

Solve for Position M - Calculate the current on the DVM

Use the smallest value from the three meters. 

Solve for Position P - Calculate the current on the DVM

DVM1 minus DVM2 is the value you seek. 

Solve for Position E - Calculate the current on the DVM

Calculate the values displayed among the three meters and use the lowest one.

Solve for Position R - Calculate the current on the DVM

Use the most-significant-bit from your calculation to get the value you need.

Solve for Position E - Calculate the current on the DVM

Use the lowest value you calculate will be displayed among the three meters.

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