If the student observes a curved I-V graph for a metallic conductor at a constant temperature, rather than the expected straight line, this suggests that the conductor is not behaving as an ideal Ohm’s conductor over the range of applied voltages. A few possible explanations for this observat...

Ohm’s law states that the current (I) flowing through a conductor is directly proportional to the potential difference or voltage (V) applied across it, for any given temperature. The constant of proportionality is called the resistance (R) of the conductor. ...
