As I used different lengths of wire for each trial there is the additon of an unwanted length variable, which to control, must be normalised. In doing this, I calculated the normalised resistance of each wire, assuming a constant length and thickness for the wire, with only resistivity varying.

In order to calculate current density, the current through the circuit is required, which, along with voltage, would have been affected when resistance was normalized. Is there any way to calculate normalised current when only normalised resistance has been determined?

Thanks.
