a student has various metal rods of known dimensions and wants to determine whether the rods are made of the same metal by determining their resistivities. the student plans to connect the circuit shown above, record the potential difference of the power source, and use the meters to measure the potential difference across the resistor and the current. will the measurement allow the student to determine whether the rods have the same resistivity, and why or why not?
