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.
What happens to the current as the resistor approches infinty?
Most resistors are linear, or 'ohmic', devices -which means that they obey Ohm's Law. So the ratio of voltage to current remains constant for variations in voltage. In other words, their resistance remains constant -providing their power rating isn't exceeded. So you can say that, providing the current increase doesn't cause their power rating to be exceeded, their resistance should remain the same. Resistors wouldn't be of much use if their resistance value changed whenever the current through them changed!
What is ohmic decay?
Ohmic decay is the wasting away of dipolar magnetic fields. This decaying takes place over a very long period of time.
Is LDR an ohmic conductor?
A Light Dependent Resistor (LDR) is not considered an ohmic conductor. Ohmic conductors follow Ohm's Law, where the current through the material is directly proportional to the voltage across it, resulting in a constant resistance. In contrast, the resistance of an LDR changes with varying light intensity, leading to a non-linear relationship between voltage and current. Thus, its behavior does not conform to ohmic characteristics.
Are fixed resistors ohmic?
yes
Will the resistors ohmic value increase if you increase the voltage?
No.
Why are ohmic materials useful?
because ohmic materials such as resistors can be placed in ur bedroom for safe sex
Resistors which have only one ohmic value are called?
Fixed
What type of resistors can only have one ohmic value?
Fixed resistors have a single, predetermined ohmic value. These resistors come in various types such as carbon film, metal film, and wirewound, and their resistance value does not change once manufactured.
What are non ohmic devices give an example?
non ohmic devices are diodes, LED's, Thermistors, LDR(light dependent resistors, cells in series.
Is Thermistor ohmic or non-ohmic?
no.....thermistors are not ohmic.
What is ment by high resistance and low resistance on a meter?
On a multimeter, a high resistance would indicate a high Ohmic value and a low resistance would indicate a low Ohmic value. Specific values would be relative to device you are measuring.

What are ohmic and non - ohmic conductors?
ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
Differentiate between ohmic and non ohmic substances?
which law follow non ohmic substances
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.
