Ohm's law - Wikipedia
An element (resistor or conductor) that behaves according to Ohm's law over some operating range is referred to as an ohmic device (or an ohmic resistor) because Ohm's law and a single value for the resistance suffice to describe the behavior of the device over that range.
What is an Ohmic Resistor? - Techwalla
An ohmic resistor is made ohmic because its function follows Ohm's law. Ohm's law essentially says that current is equal to voltage divided by resistance. Additionally, resistance is equal to voltage divided by current, and voltage is equal to current times resistance.

Ohmic materials have a resistance R that is independent of voltage V and current I. An object that has simple resistance is called a resistor, even if its resistance is small. Voltage Drop: The voltage drop across a resistor in a simple circuit equals the voltage output of the battery.
Ohm’s Law | Resistor Fundamentals | Resistor Guide - EE Power
A resistor that functions according to Ohm’s law is called an Ohmic resistor. When current passes through an Ohmic resistor, the voltage drop across the terminals is proportionally to the magnitude of resistance.
9.5: Ohm's Law - Physics LibreTexts
The current through the resistor and the voltage across the resistor are measured. A plot is made of the voltage versus the current, and the result is approximately linear. The slope of the line is the resistance, or the voltage divided by the current. This result is …
What is an ohmic resistor? How to check if a resistor is ohmic?
An ohmic resistor is a resistor that obeys Ohm's law V = IR (voltage = current x resistance). Therefore, if the voltage in such element is increased by n number of times, by the same number n has to increase the current. To determine if a resistor is ohmic, voltage in a resistor needs to be changed and both voltage and current have to be meassured.
What is the ohmic resistor? - Physics Network
May 16, 2023 · An ohmic resistor is a resistor that obeys Ohm’s law. For example: all metallic conductors (such as silver, aluminium, copper, iron etc.) The slo [e of the V-I graph gives the resistance.
Resistors | Ohm's Law | Electronics Textbook - All About Circuits
Jan 14, 2022 · Special components called resistors are made for the express purpose of creating a precise quantity of resistance for insertion into a circuit. They are typically constructed of metal wire or carbon and engineered to maintain a stable resistance value over a wide range of environmental conditions.
Ohm - Wikipedia
The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt (V), applied to these points, produces in the conductor a current of one ampere (A), the conductor not being the seat of any electromotive force. [ 1 ]
