Ohmic material
A ohmic material is a Matériau which shows the Loi of Ohm compared to the relation between the Electric current through this one and the voltage which passes to him above.
This law is , where V represents the tension, I represents the intensity of the electric current and R represents the resistance.
No materials can show ideal resistance describes by the law of Ohm, but there is in has several which can imitate it. Some examples of Ohmique materials are resistances and of the wire driver. An good example of an not-Ohmic material is a bulb since the current heats this one and its resistance depends on its temperature.
The semiconductors having a level of high doping (also called contacts ohmic) approaches the answers ohmic, though the areas having a level of average doping depend enormously on the voltage.
