Physics ohm law

Ohm's law definition: the principle that the electric current passing through a conductor is directly | meaning, pronunciation word lists physics terms. Ohm's law states that the current through a conductor between two points is directly in physics, the term ohm's law is also used to refer to various generalizations of the law originally formulated by ohm the simplest example of this is. Often referred to as the ohm's law equation, this equation is a powerful predictor of the relationship between potential difference, current and resistance. By looking at a number of examples of non-ohmic behaviour, students can learn to distinguish between the definition of resistance (r = v/i) and ohm's law (r is.

Example: a two ohms resistor two ohms means you need two volts per ampere so if you want 10 amperes to flow through the resistor you.
