Question

under what condition is Ohm's law applicable

Answer 1

Hey there,

Ohm's law is only applicable under constant temperature, mechanical stress and strain. Then only the ratio of V and I will be constant.

Besides this, Ohm's law is also not applicable to semiconductor band conductors and volatile conductors due to random lattice movement.

Liquids follow Ohm's law up to some extent but can too be disregarded as they too have random kinetic energy of molecules.
