Discuss what in particular makes the light bulb a non-ohmic resistor. specifically, how does temperature affect resistance? can thermal expansion explain the non-ohmic behavior? if not, describe what happens at the atomic level that accounts for the non-ohmic property

the loss of energy due to the Joule effect is the cause of the non-ohmic characteristic of the bulb

Explanation:

A resistance is formed of some type of metal, in a light bulb it is Tungsten, which for low current is a resistance that complies with the ohm law.

When the value of the current is increased the shock of the electors creates a Joule effect, which heats the metal, these shocks are due to atomic imperfections of the structure, this heating creates a loss of energy of the system that causes the characteristic to be lost linear between the voltage and the current, since the total energy balance must be preserved.

An approximate measure of the energy that is emitted is given by Stefan's law.

In short, the loss of energy due to the Joule effect is the cause of the non-ohmic characteristic of the bulb
