1. The problem statement, all variables and given/known data A wire, 50.0 m long and 2.00 mm in diameter is connected to a source with a potential difference of 9.11 V, and the current is found to be 23.45 A. Assume a temperature of 20°C and using Table 17.1, identify the metal out of which the wire is made of. 2. Relevant equations R=p(l/A) where R is the resistance p is the coefficient of resistivity, l is the length and A is the area 3. The attempt at a solution ok since we are solving for p first i found R by the equation V=IR and found R to be .388 next i found the area using the surface area of a cylinder and found that to be .628 next i divided length by .628 and found that to be 79.618 so then i divided .388/79.618 and got 4.8*10^-3 thats the right magnitude but it does match any of my options coefficients. the problem lets me choose whether the metal is gold, silver, copper, or iron.
