Astudent conducted an experiment to determine the resistance of a lightbulb. while performing the experiment the student noticed that the lightbulb began to glow and became brighter as she increased the voltage. of the factors affecting resistance, which factor caused the greatest change in the resistance of the bulb during her experiment?
im not sure about the it voltage, temperature, or the resistance?
temperature affected the bulb greatly. i need with energy

Explanation :

In this experiment, the student noticed that the light bulb began to glow and became brighter as she increased the voltage. The greatest change in the resistance of the bulb is caused due to increasing temperature.

The temperature depends directly on the resistance. It can be shown from the following relation :

Where

are resistance and temperature of reference material.

It is clear that when the temperature increases, the resistance also increase. Due to this, the bulb starts getting hotter.
