Ohmic potential refers to the voltage drop across a conductor due to its resistance when an electric current flows through it, following Ohm's Law (V = IR). This potential is directly proportional to the current (I) and the resistance (R) of the material. In practical applications, the ohmic potential is essential for understanding how electrical circuits behave under different loads and conditions. It is a key factor in designing efficient electrical systems.
no.....thermistors are not ohmic.
the resistant in ohmic devices is constant because it depend on temperature ..and temperature is constant independent of polarity of potential difference...btin non ohmic the tempt increase with voltage which increase due to the heat increase beacue of power dispition....collision of electrons increases find more resistenc for passing so resistence increases
ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
which law follow non ohmic substances
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
iron,gold
ohmic conductors are those which obey ohm's law
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.
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.
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:)
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.
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.
