Question

Is Ohm's law universally applicable? If the V-1 graph is not linear for a given material, writethe name of the material.​

Answer 1

Answer:

Ohm's law is not universally applicable forall conducting elements. For example Ohm's law does not hold true for vacuum tubes, semi-conducting diode, liquid electrolyte etc. These are non-ohmic elements.

Explanation:

if the v-1 graph I'd not linear for the given material,it is a non ohmic substance...(the ones who don't follow ohms law)

if the v-1 graph I'd not linear for the given material,it is a non ohmic substance...(the ones who don't follow ohms law)I hope this helps.

Answer 2

Explanation:

ohms law is not universally applicable for all conducting elements vacuum diode semiconductor,nichrome is a non ohmic conductor ohms law is not valid for it.

ohms law is not applicable to non linear elements are those which do not have current exactly proportional to the applied voltage
