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.
Is a ceramic resistor ohmic?
yes
What is the difference between resistor and metrosil?
Resistors are ohmic and fixed whereas metrosils are non ohmic and variable - version of a varistor.
Example of non -ohmic and ohmic materials?
iron,gold
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 the 10 ohm resistor ohmic or non-ohmic?
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.
Is resistor an ohmic device in ac circuit?
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
How can you check if 50 mega ohms resistor is open?
use a merger tester, if there are no indication to certain number of ohmic (50 M), that is mean resistor is open.
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.
Is Light dependent resistor an example of resistor?
yes, a variable resistor
2 resistors unequal value are in parallel. Would the power dissipated by the resistor with larger ohmic value be greater than the power dissipated by the resistor of lesser value?
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.
