Liquids obey Ohm's law partially.

Vedclass · Answer

(B) Ohm's law states that the current flowing through a conductor is directly proportional to the potential difference applied across its ends,provided the physical conditions remain constant. This results in a linear $V-I$ graph. For liquids (electrolytes),the relationship between current and potential difference is generally non-linear due to factors like polarization and chemical changes at the electrodes. Therefore,liquids do not follow Ohm's law strictly,meaning they obey it only partially or under specific,limited conditions. Thus,option $B$ is correct.
