Ohmic resistors or conductors follow the Ohm's law V = R I.
Non-Ohmic conductors have resistance, and pass electricity but they do not follow the law above.

OHMIC CONDUCTORS are those which follow Ohm's law i.e. V=IR
at constant temperate.
They have a linear graph between Voltage(V) and Current(I).
Eg. Copper wire.
NON-OHMIC CONDUCTORS are those which don't at all obey Ohm'slaw.
Their V-I graph is non-linear.
Eg. PN Junction diode, Transistors etc.
