Geocache Description:

City of Ramsey River Bend Park.

Not at the listed coordinates.

I rated the terrain high because I think when it gets to be snow
and ice it could be hard to get to from the parking lot. It might even be hard if the leaves are wet.

Park at the given coordinates. There you will find a nice kid's playground, a pavilion area with picnic tables and in season a port-a-potty.

Basic electronics:

         The simplest of electronic circuits contain only two components,
a power source like a battery and a load like a light bulb.

To be practical you will need a conductor as in wire and optionally
a means of control like a switch. 
A power source is either electromechanical as a generator, or wind
turbine, or electrochemical as in a battery. 

A load is something that requires an electric current to operate. A radio.
lamp, a clock or computer. Or a resistor, anything that uses electricity
and produces heat.

A conductor is any substance that allows electrons to pass freely, usually
metal like copper. The opposite of a conductor is an insulator, something that
blocks the flow of electrons as plastic or rubber. 

A power source like a battery has the capacity to force electrons around this circuit.
It is sometimes called an Electromotive force or EMF. Often heard of as a Potential
difference.  This is measured in VOLTS.

The amount of electrons flowing around in the circuit is a CURRENT. Any amount
Of current is measured in Amperes or amps.

The amount of opposition to that flow of current offered by the load is calls resistance.
Resistance is measured in Ohms. 

The amount of energy consumed by an appliance is called Power and is measured in Watts.

 All of these terms are taken from scientist who worked with the discoveries of the properties 
of electricity. Voltaire, Ohm, Watt and others.  

The formula Ohms law is E= I * R or The Electrical Potential (E) measured in Volts is
Equal to the current (I) measured in amps flowing through a resistance(R) in ohms.

 Example: If there is a battery potential of 3 volts and a lamp with a resistance of 2 ohms
Is connected to it there will be a current of 1.5 amperes flowing through it.  
 E=3, R=2 a bit of algebra and I=E/R so I=3/2=1.5

More practically a 12 volt battery and a lamp drawing only a quarter (.25) amperes of current 
would have a resistance of 48 ohms. Algebra again, R=E/I or 12/.25 = 48 ohms.

POWER as measured in watts is like the watt-Hour meter outside your house it is a combination 
Of the potential of the electricity provided (110-122 volts) and the current used by all the gadgets.
 in your home all measured in Watts. Power measured in watts is equal to E measured in Volts times
current (I) measured in amperes. Or P=I * E.

Example: 12 volts times .25 amperes equals 3 watts of power consumed.

Formulas used here E=I*R and P=E*I
E=electric potential in Volts like a battery
I=current through a device measured in amperes
R=resistance measured in ohms
P=power in watts

  Calculate the following values.
   ________V1= voltage of 0.325 amperes flowing through a 40 ohm resistor
   ________I1= current through a 20 ohm resister with a 13.08 volt battery
   ________P1=power in watts produced by 115 volts with 0.2 amperes of current
   ________R1=resistance of load if 14.82 volts produces a current of  20 amperes

So now go to North 45 :V1I1 by West 93:P1R1
