| - | Here are some notes on the fundamentals of electricity and some reference items: | ||
| - | |||
| - | | [[resistance|Resistance]] | Ohms | R | | ||
| - | | [[current|Current]] | Amps | I | | ||
| - | | [[voltage|Voltage]] | Volts | V | | ||
| - | | [[power|Power]] | Watts | P | | ||
| - | |||
| - | The relationship between these is fundamental to electronics and the basic law (Ohm's law) is: | ||
| - | |||
| - | Voltage = Current * Resistance | ||
| - | |||
| - | or | ||
| - | |||
| - | V = IR | ||
| - | |||
| - | To derive the power being used we can multiply the pressure by the flow or the voltage by the amps: | ||
| - | |||
| - | Power = Volts * Amps | ||
