It depends on whether the material is ohmic or non-ohmic.If it is ohmic, then it will obey Ohm's Law, and its resistance will remain constant if the current decreases.If, on the other hand, it is non-ohmic, it will not obey Ohm's Law and, if the temperature of the conductor falls (assuming it is a metallic conductor) due to the fall in current, then its resistance will fall too.
An ohmic resistor is a resistor that obeys Ohm's law, and a non-ohmic one dose not. All resistors resistance will begin to change as there temperature changes, and often we need a resistor with a steady resistance, thus some resistors, which we refer to as ohmic, will disperse the heat being generated and therefore it will keep a steady resistance. Resistors that do not disperse their heat will have varying resistances and therefore are non ohmic. Ohms law, named after the German physicist Georg Ohm, states that the current through a conductor, between two points, is directly proportional to the potential difference (voltage) across the two points, and inversely proportional to the resistance between them. ~Ben Frilay-Cox
An 'ohmic' resistor is one which obeys Ohm's Law. For Ohm's Law to apply, the resistance of a circuit must be constant over the range of incremental voltages applied to it. If the resistance changes over an incremental range of voltages, then it is said to be 'non-ohmic', and it does not obey Ohm's Law.
Ohm's law states that the current and potential difference (voltage) are directly proportional, provided the temperature is constant. The resistance of a thermistor is dependant on the temperature, so it does not obey Ohm's law. Components that do not obey Ohm's law are non-ohmic conductors.

A filament lamp is a non-ohmic conductor because its resistance changes with applied voltage. As the voltage increases, the resistance also increases. This is due to the temperature-dependent behavior of the filament material, which causes the resistance to vary.
ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.

Vacuum tubes are non-ohmic devices because their resistance changes with voltage and current. This non-linearity in resistance is due to the nature of the electron flow within the vacuum tube, causing it to exhibit non-ohmic behavior.
Diode is a non-ohmic conductor since in diodes current-voltage relation ship does't obey Ohm's law....the relationship between current and voltage is nonlinear here,...

ohmic ocnductor is a material which obeys ohm's law: i.e. the voltage and current are directly proportional 2 each other anda non-ohmic ocnductor is a material which doesn't obey ohm's law:)
A 'non-ohmic' conductor is one that does not obey Ohm's Law -i.e. the ratio of voltage to current is not constant when the voltage across it varies.
A 10-ohm resistor is considered ohmic if its resistance remains constant regardless of the applied voltage or current. Ohmic behavior indicates a linear relationship between voltage and current, following Ohm's Law (V = IR). If the resistance of the 10-ohm resistor remains consistent regardless of changes in voltage or current, then it can be classified as ohmic.
