Resistance of a wire investigation apparatus. Four wires, 50cm long mounted on a hardwood and acrylic base with connection made by a 4mm socket. The wires are all nichrome with differing diameters (1.0, 0.8, 0.63, and 0.4mm) giving resistances in the range 1.4 to 4 ohms. A graduated mm scale is included allowing distance vs length and resistance vs diameter to be investigated easily. Board dimensions 540 x 90 x 25mm
