The common term for electrical pressure is voltage. Voltage is defined as the amount of electrical pressure that results in 1 ampere given a resistance of 1 ohm, according to Bay Electric.
Continue ReadingOhm's law states that I (amperes) is equal to V (voltage) divided by R (resistance); in short, I = V/R. As such, voltage is directly proportional to the amount of resistance in a given circuit, or more simply stated, as resistance increases, voltage goes down. If considering the flow of electricity to be similar to the flow of water through a hose, increasing resistance would be analogous to placing a finger over the end of the hose, thus reducing flow.
