    hey all,

    I'm doing a piece of As Coursework that my teacher made me do, the thing i wanted 2 do he said was too simple.....

    ANYWAY.....I used a mirror Galvanometer and a thermocouple thermometer and took results of how the numbers on glavanometer changed as i varied temperature..........anyone got any ideas wot this was measuring, or exactly what I was doing?

    Galvanometers measure current. You probably noticed that as the temperature increased, the current decreased. This would be because the resistance in the circuit increased (due to atoms vibrating more, hence making it more difficult for the electrons to flow).
