Answer:
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
From that ragged, motley list of statements, only 'C' is true.

Answer:
B
Explanation:
Heat flows from hot to cold to lower the temperature of hot areas and increase temperature of cold areas. The end result is that the 2 areas have the same temperature, thus increasing entropy.
