### Definitions

noun

(Electrical engineering: Circuits, Electrical power, Computing and control) Ohm's law is a law that states that the voltage across a resistor is directly proportional to the current flowing through the resistance. Ohm's law is named for German physicist Georg Ohm (1789-1854). ⇒ A simple formula, Ohm's law, is used to show the relationship of current, voltage, and resistance. ⇒ We can calculate, using Ohm's law, what resistor is needed to get a specific current. ⇒ Ohm's law is a law that states that the voltage across a resistor is directly proportional to the current flowing through the resistance.
