Question

In ohm law verification temperature remain constant. why?

Answer 1

Ohm´s Law states that: "In metallic conductors at a constant temperature and in a zero magnetic field, the current flowing is proportional to the voltage across the ends of the conductor, and is inversely proportional to the resistance of the conductor.

Answer 2

Resistance is directly proportional to length of the conductor and inversely proportional to the area of cross-section of the conductor. ... Constant temperature makes the resistivity constant which made resistance constant. Constant resistance again made the Ohm's law applicable.
