Copper and aluminum are being considered forahigh-voltagetransmission line that must carry a current of 60.0A.Theresistance per unit length is to be .150 ohm/km. Whatisthemagnitude J of the current density for each material?
I really don't know how to get this. I've looked uptheresistivitiesof each material but don't know how to find Jwithoutdetermining theelectric field, and I don't have theinformation toget E.
