They are Voltage (V) or (E), measured in Volts, Current or Amperage (I), measured in Amps (Amperes), and Resistance (R) measured in Ohms. The third factor will be calculated for you when you click on the Calculate button for that table. Ohm's Law is V = I x R where V = Voltage, I = Current and R = Resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere.

Leeches (Hirudinea) Leeches are a class of segmented worms closely related to aquatic earth worms that live primarily in freshwater, although some marine and terrestrial species exist.
