Question

Do all conductors obey Ohm’s law? Give examples to support your answer

Answer 1

Not all conductors obey Ohm's law. In fact, most conductors of electricity are non-ohmic conductors. Ohm's law is only true for resistors whose resistance does not depend on the applied voltage, which are called ohmic devices. ... With non-ohmic conductors, resistance depends on voltage and is no longer a constant.

Answer 2

Answer:

No. Not all the conductor obey ohms law. The material that obey ohms law is known as ohmic conductor and the substance that does not obey ohms law is known as non ohmic conductor. Aluminium, silver, copper are ohmic conductor while rubber, wood, plastic are non ohmic conductor
