Experiment to find the relationship between power Applied and potential difference Introduction In this experiment we had to investigate how the power dissipation of a filament lamp varied with different potential differences across the circuit. Also to find a relationship between the power and potential difference, from this information draw a graph and collect suitable results. Method I connected a power supply to a filament lamp (10v maximum output) this was then connected to an amp meter this was then connected back to the power supply. The voltmeter was connected in parallel. Then I set the power supply to 0v then turned it on then increased the voltage in 1 volt stages starting at 1 volt and finishing at 8v taking the readings from the amp meter and recording them on a table. I repeated this part twice to make sure my readings where accurate and also to give me and average reading. From...
