hi, we have been given the task title of "investigate a factor that may affect the resistance of a filament bulb" for our additional physics practical assessment.
Just wandering if anyone could help me with this.
I will need to give a hypothesis, 2 methods and there research sources, the equipment used, risk assessment issues and a context, etc.
some research sources plus any other help would be great!
Thanks
