If you have several wires made from different Ohmic materials with different lengths L, different radii r, and different resistivities p, and you perform an experiment in which you connect wires in series with a power supply with a variable emf and measure the current I and the potential difference V across the wires. Then you obtains a linear relation between: O a. the current and the length of the wire using a power supply with a fixed emf and wires from the same material with equal radius. O b. the resistivity and I using wires from different materials with equal lengths and radii and fixed emf of the power supply. O c. V and I using wires with equal length and made from different materials. O d. the current and the inverse of the resistivity, using a fixed emf of the power supply and wires of equal length and radius made from different materials. O e. the potential V and the current la variable emf of the power supply and wires of equal length and radius but made from different materials.
