How can you verify that the resistance of a conductor is temperature dependent?

a. A bulb was taken and its resistance was measured using a multimeter in open circuit.

b. The bulb is connected to a circuit and switch is put on.

c. The bulb glows and after few minutes it gets heated up.

d. Again the resistance of the bulb is measured using a multimeter.

e. Value of resistance is found to be more in the second case than in the first case.

f. As the temperature of the filament in bulb increases the resistance of bulb also increases.

Thus we can say resistance of a conductor is temperature dependent.
