An excellent introduction to the process of finding an unknown resistance using the aid of the Wheastone Bridge. A one meter long resistance wire is stretched taunt across a meter stick mounted on an anodized aluminum base. Binding posts are connected on each end for convenient connection. A knife edged switch slides freely across the meter stick for varying the resistance of the wire. An aluminum bar with binding post runs across the top of the unit to provide known, equal resistance.
