Want this question answered?
A non-ohmic resistor doesn't have a constant resistance. A ohmic resistor has a constant resistance.
yes
i give the ans why iam asking you
Resistors are ohmic and fixed whereas metrosils are non ohmic and variable - version of a varistor.
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.
If it has constant temperature (one can do this by dipping it in a beaker of water) it can be considered an ohmic conductor since Ohm's law states that the Voltage and amperage are directly proportional in a metallic conductor of constant temperature.
Well, yes, sort of. "Ohm" is a measurement of resistance, so I would say yes. Although I'm not sure of 'ohmic' is really a word
use a merger tester, if there are no indication to certain number of ohmic (50 M), that is mean resistor is open.
no.....thermistors are not ohmic.
No, because the power dissipated in a resistor is proportional to the square of the current through the resistor but only directly proportional to the resistance of the resistor (I^2 * R) and the current through the lower value resistor will be higher than the current through the higher value resistor, the lower value resistor will usually dissipate more power.
Vacuum tubes are non-ohmic devices
ohmic conductor does obey ohm 's law. non ohmic conductor does not obey ohm's law.
