A device for demonstrating the dependence of conductor resistance on its length, cross-section and material

The set includes: the device (assembled) - 1 piece, an instruction manual in Kazakh and in Russian – 1 pc.

The device should be a wooden panel with terminals, between which four wires of the same length (1 m) should be fixed: one of copper, the second of iron, and two of nichrome (of different diameters). 

The device should also indicate the cross-sectional area of each wire, which corresponds to diameters of 0.25 and 0.5 mm. To demonstrate the dependence of the resistance of the conductor on it length, section and material.
