when is it more likely for the filament of a light bulp to break
Here is probably more than you ever wanted to know and more.

Resistance is a measure of the opposition to the flow of electric current. It is represented by the symbol "R" and is measured in ohms (Ω).
As temperature increases, the resistance of a material also increases. This is because as temperature rises, the atoms in the material vibrate more, causing more collisions and hindering the flow of electric current.
The relationship between resistance and temperature is directly proportional. This means that as temperature increases, resistance also increases.
Resistance is important in electronic circuits because it helps to control the flow of electric current. It also helps to prevent damage to components by limiting the amount of current that can pass through them.
The resistance of a material can be calculated by dividing the voltage (V) by the current (I). This is represented by the formula R=V/I. However, the resistance of a material can also be affected by factors such as length, cross-sectional area, and temperature, so more complex formulas may be necessary for accurate calculations.
