| Wheatstone Bridge
|
| 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. A aluminum bar with binding post runs across the top of the unit to provide known, equal resistance. |
