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.
Is carbon resistance is a non ohmic conductor?
Yes, carbon resistance is considered a non-ohmic conductor. Unlike ohmic materials, which follow Ohm's Law (V = IR) with a constant resistance, carbon's resistance can change with temperature and the applied voltage. This means that its current-voltage relationship is nonlinear, characteristic of non-ohmic behavior.
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.
What is the example of ohmic material?
Metals like copper, silver, gold, iron, etc are examples of ohmic metals.Another AnswerThere are very few ohmic materials. Ohmic materials are those that obey Ohm's Law, and very few do -which might come as a surprise to many people (Ohm's Law is NOT universal law!)! For a material to obey Ohm's Law, the ratio of voltage to current must remain constant for variations in voltage. Because increasing current causes increasing temperature, the resistance (and, therefore, the ratio of voltage to current) of most materials will change for variations in voltage.So, an ohmic material must maintain an approximately-constant resistance over a wide range of temperatures -so metals such as copper, silver, gold, etc., do NOT qualify! However, alloys such as constantan (a nickel-copper allow) would qualify as being ohmic.
What is Low OHMIC?
Low ohmic refers to materials or components that have a low electrical resistance, typically measured in ohms. Such materials allow electric current to flow more easily, leading to increased conductivity. Low ohmic components are often used in applications where minimal energy loss and efficient current flow are essential, such as in power distribution systems and electronic circuits.
Is Thermistor ohmic or non-ohmic?
no.....thermistors are not ohmic.
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.
Example of non -ohmic and ohmic materials?
iron,gold
What is an ohmic conductor?
ohmic conductors are those which obey ohm's law

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.
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:)
When the voltage across the ends of a piece of wire is doubled what effect does this have on the current in the wire?
current doublesAnswerIt depends on whether the wire is ohmic or non-ohmic. If it is ohmic, then the current will also double. If, like tungsten, it is non-ohmic, then it depends.... because doubling the voltage will cause its resistance to increase.Ohmic materials obey Ohm's Law, whereas non-ohmic materials do not.
Why are ohmic materials useful?
because ohmic materials such as resistors can be placed in ur bedroom for safe sex
What happens to the resistance of a common ohmic resistor when it is heated?
When a common ohmic resistor is heated, its resistance typically increases.
