Ohm's Law Calculator Ohm's Law Calculator Enter any two known values and press "Calculate" to find the other 2 values.  Reset the field to 0 before each new calculation.    Volts (E) Amps (I) Ohms (R) Power (Watts)

Understanding Electricity-

 

If electricity were a fluid like water then:

 

Volts = PSI
Amps = GPM potential
Watts = GPM delivered
Wire size = Pipe size

Ohms = Friction losses due to length + diameter of pipe

 

With more PSI you can pump more fluid through smaller pipe.

That is why lower voltages require larger wire (larger pipe) size.

 

MORE:

 

Wire = Pipe

Capacitor = Rubber bladder

Resistor = Flow reducer

Diode = Check valve

Zener Diode = Faulty check valve

Transistor = Gate valve

Potentiometer = Diversion valve

 

 

Other stuff on the edge of explanation as a fluid -

 

Induction = Sponge

Magnetism = ?????
