If you decrease resistance the current will increase or decrease?
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.
What is the definition of an ohmic conductor?
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
What is the difference between ohmic and non ohmic elements?
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.
Why is a thermistor a non ohmic conductor?
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.
What is the Illustration of ohm's law?
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points, and inversely proportional to the resistance between them
Why is a filiament lamp a non ohmic conductor?
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.
What are ohmic and non - ohmic conductors?
ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
What is the difference between an ohmic resistor and a non-ohmic resistor?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
If you decrease resistance the current will increase or decrease?
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.
Is vacuum tube ohmic or non-ohmic and why?
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.
Is diode ohmic or non-ohmic conductor?
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,...

What are Ohmic and Non - Ohmic conductor?
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:)
What is non ohmic material?
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.
Is the 10 ohm resistor ohmic or non-ohmic?
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.
