Wheatstone Bridge

Used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component. This wheatstone bridge consists of an aluminium base with a length of constantin wire mounted alongside a metre rule and terminated with 4mm screw posts. Each end is effectively connected together to form the bridge but with 4 gaps to allow the insertion of known or unknown resistors. It is supplied with a jockey for taking readings along the meter scale.
