Lascells Resistance Wire Board

The Resistance Wire Board provides the basis for student investigations into resistance. Four wires, 50cm long mounted on a hardwood and acrylic base with connection made via a 4mm socket.

The wires are all Nichrome with diameters of 1.0, 0.8, 0.63 and 0.4mm giving resistances in the range 0.4 to 4 ohms. A graduated mm scale is included allowing resistance vs. length and resistance vs. diameter investigations to be easily covered.
