Answer
The conductors which obey the Ohm's law are called the ohmic resistors or linear resistances. Examples are all metallic conductors (such as Silver, Aluminium, Copper, Iron etc.)
Current–Voltage relationship of an ohmic resistor is shown in the below graph:
Resistance is determined in the form of slope from the graph.
