Hello. I had to do an important science investigation in school. The title I was given was 'Investigate the relationship between the size of the electric current passing through a length of wire and its heating effect'.
I devised a circuit where I could change the resistance as well as measure the current and by how much a length of nicrome wire heated up a certain amount of water by in ten minutes.
However I messed up and lost my results. I know that a graph of temperature change and current should not be a straight line and that you need to do a conversion to do with power to get directly proportional results.
Could anybody tell me the conversion I need to do and give me some ready made results of current and temperature that will work out after the conversion. Bearing in mind that I need 5 results and I used a 6 v battery.
I am very grateful for any help.
