WebNov 25, 2024 · Ohm’s law specifies the relationship between current, resistance, and voltage. This law states that the current passing through a conductor is directly proportional to its voltage, i.e., I=V/R Power Power (P) is a measure of the quantity of work a circuit can do, or a component can consume per unit time. WebOhm’s Law - How Voltage, Current, and Resistance Relate. PDF Version. The first, and perhaps most important, relationship between current, voltage, and resistance is called Ohm’s Law, discovered by Georg Simon Ohm and published in his 1827 paper, The Galvanic Circuit Investigated Mathematically.
