1. The problem statement, all variables and given/known data For what electric field strength would the current in a 2.0-mm-diameter nichrome wire be the same as the current in a 1.0-mm-diameter gold wire in which the electric field strength is 0.0095 N/C? dn = .002m dg = .001m Eg = .0095 N/C ρn = 100 * 10-8 Ωm ρg = 2.44 * 10-8 Ωm 2. Relevant equations V = IR R = ρL/A V = E * Δs 3. The attempt at a solution First, I found a general equation for current in a wire: V = IR I = V/R I = (E*Δs)/(ρL/A) I = EA/ρ Then, I used this to find the current in the gold wire (and by extension, the nichrome wire). In = Ig = Eg * Ag / ρg I then used the I = EA/ρ equation to find an expression for the electric field in the nichrome wire, and plugged in the above value for the current. En = In * ρn / An En = (Eg * Ag * ρn) / (ρg * An) I then plugged in the values and solved. En = [(.0095 N/C)(π*(.001m)2/4)(100*10-8Ωm) / [(2.44*10-8Ωm)(π*(.002m)2/4)] = .0973 N/C Webassign is not accepting this answer. Does anyone know where I went wrong?
