Resistor which follows the ohm's law is called ohmic resistor.
Ohmic resistors have constant resistance.

Ohmic resistors are those resistors that have a constant resistance. In other words, the follow the Ohm's law. If you take such a resistor, apply voltage across it, whilst measuring current and voltage, and then draw a graph of current versus voltage, you get a straight line.

samitsrivastav: rheostat is variable resiator

Anonymous: A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption. ... Therefore they are mostly constructed as wire wound resistors. Resistive wire is wound around an insulating ceramic core and the wiper slides over the windings.

samitsrivastav: means resistor whose resistance can be changed

samitsrivastav: yes
