How does the resistance of a resistor behave if the temperature remains constant?

When the temperature of a resistor remains constant, its resistance also remains constant. This is due to the fundamental property of resistors, which are designed to follow Ohm's Law, where the relationship between voltage (V), current (I), and resistance (R) is defined as V = I × R. In this context, if the temperature does not change, the material properties of the resistor—particularly the conductivity and resistivity—stay the same, maintaining a stable resistance.

In practical terms, this means that for a given voltage applied across the resistor, the current flowing through it will not cause any fluctuations in resistance. Therefore, the resistance remains consistent irrespective of the changes in current under these conditions. This stability is essential in many electronic designs where predictable behavior of components is critical for reliable operation.
