    Electric Potential Difference Problem

    So it seems like it is a one dimensional problem. Have you been introduced how to calculate electrical fields yet ?

    A copper wire and an iron wire - Potential difference

    On the right track , try to Calculate Rcopper and RIron and the current separately. I think you are supposed to find the conductivity of Iron and copper in your book as they are not stated in the problem.

    A copper wire and an iron wire - Potential difference

    Ah... I think its a remix of Ohm law, V=RI , where they have rewritten the resistance as L/(σ*A) , where σ is the conductivity of a given material. I not entirely sure tho, some units on the calculations would have helped a lot hehe

    A copper wire and an iron wire - Potential difference

    How did you come up with with your solution attempt and what are your thoughts behind it ?
