Final answer:

To demonstrate how wire resistance changes with temperature, set up a circuit with a wire, power supply, ammeter, and voltmeter, observing how current and voltage readings vary with temperature.


Explanation:

Experiment Setup: To demonstrate how the resistance of a wire varies with temperature, set up a circuit with a power supply (cell), an ammeter, a voltmeter, and the wire to be tested. Connect them in series.

Procedure: Heat the wire using a heat source such as a Bunsen burner. Measure the current using the ammeter and the potential difference using the voltmeter as the wire's temperature increases.

Observation: As the temperature rises, you will notice a corresponding increase in resistance, leading to changes in current and voltage readings.
