For the resistance of a wire coursework, i have already done it based on experimenting with different lenghts against resistance. for the evaluation, i need to write an extension on the coursework: i have a few ideas already • Experimenting with other types of materials of wires to see if they follow the same pattern. • Find out if non-metallic conductors follow the same pattern as well. • Find out if there is a relationship with current, resistance and voltage. The experiment can be set up like the potentiometer circuit. the problem is that i need to come up with a mini-method for one of them, but im right confused on that, any ideas? it would also be great if its for the first bullet pint Thanks!
