Why Does the Resistance of a Filament Lamp Increase? WORKED EXAMPLE - GCSE Physics

This video is a worked example for a descriptive question about resistance. This is a popular type of question for students to be asked and this one in particular is specific to explaining the behaviour of a filament lamp's resistance as the potential difference across it changes.

The questions is as follows:
Explain why the resistance of a filament lamp increases with potential difference.
