2305 Wheatstone Bridge
This Slide wire Wheatstone Bridge consists of a resistance wire with a sliding contact and a strip of aluminum to provide two "arms" of the bridge for known and unknown resistances. This apparatus also allows students to visualize how the resistance of a conductor varies with its length, diameter and material for an informative lab experiment. Needed equipment: Galvanometer to show when the circuit is balanced. Instructions are included.
We have 70 skillful operators, 5 machine mechanics and 31 quality inspectors, total annual output capacity in design can reach 130 millions sets.
