Ohm's law is expressed as following:
V = R I.
Conductors which obey the ohm's laws are called Ohmic Conductors and those that don't, are Non-Ohmic Conductors.
Examples of Ohmic Conductors- Generally metals are ohmic substances at constant or small change in temperature. Wires made of copper, iron, silver etc are ohmic conductors.
Examples of Non-Ohmic Conductors- Semiconductors and insulators are non ohmic substances.
