What Is Electrical Pressure Called?

By Staff WriterLast Updated March 24, 2020

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.

Ohm’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.
