Volts - Amps - Resistance Volts - A measure of electrical pressure. Very similar to water pressure. (psi) Amperes - (Amps) A measure of electrical current flow. Very similar to water flow. (gpm) Resistance - (Ohms) Resistance to flow of electrons Very similar to friction loss in water systems.

Ohm’s Law E I R E = Volts I = Amperes R = Resistance (Ohms) Volts (E) = Amperes (I) x Ohms (R) Amperes (I) = Volts (E) / Ohms (R) Ohms (R) = Volts (E) / Amperes (I)
