A student 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 answer...is it voltage, temperature, or the resistance?
temperature affected the bulb greatly.
i need help with energy
Energy is the ability to do work. It can be found in many forms, such as kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat energy), electrical energy, and chemical energy.
To determine the factor that caused the greatest change in the resistance of the lightbulb during the experiment, let's analyze the given information. The student observed that as she increased the voltage, the lightbulb started to glow and became brighter.
Based on this observation, the factor that caused the greatest change in resistance is most likely temperature. When the voltage is increased, the current flowing through the lightbulb also increases. This increased current results in more energy being converted to heat in the lightbulb filament, causing an increase in temperature.
Temperature is known to affect the resistance of materials. In the case of the lightbulb, as the temperature rises, the resistance of the filament increases. This is because the higher temperature causes the atoms to vibrate more vigorously, obstructing the flow of electrons and hence increasing resistance.
Therefore, the increase in temperature due to the increased voltage led to a significant change in the resistance of the lightbulb during the experiment.
