Electricity practical
« on: October 29, 2017, 06:47:20 pm »

I'm doing a prac for physics about the relationship between the length of a metal wire and its resistance. I had to work out the resistance by calculating the voltage and current for each length. For the analysis section of the prac, we are allowed to bring in a raw data table and graphs. So far i have a length vs resistance graph. Would I be able to make any other graphs that would be suitable for me to analyse?

You may want to include a table showing how you have calculated resistance  (I'm assuming you used V=IR)
Make sure you are also familiar with what the r vs l graph should look like if your data was perfect
