Question

What are the conditions under which Ohm's
law is not obeyed?​

Answer 1

Answer:

See, if the physical conditions and temperature changes, Ohm's Law will not be applicable

Answer 2

Answer:

If extreme currents are applied to the wires, they heats up as a result of which their resistance changes and violets ohms law. For instance , vacuum tubes, Transistors, liquid electrolytes and so on.

Explanation:

Ohms Law states that the current flowing in a conductor is directly proportional to the potential difference across the ends provided that the physical conditions and temperature of the conductor remains constant.

V=IR     where, V= Voltage

                         I=Current

                         R=Resistance

If extreme currents are applied to the wires, they heats up as a result of which their resistance changes and violets ohms law. For instance , caccum tubes, Transistors, liquid electrolytes and so on.
