Potentiometer, 10 wire Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12410
Jlab Export is a leading Potentiometer, 10 wire Manufacturer,and suppliers in India
Potentiometer, 10 wire (code EL-PL-12410) is a slide-wire potentiometer with 10 bare constantan wires of 24 SWG, each 1 m long, laid along a rule in centimetres and millimetres on a powder-coated aluminium extrusion, with brass clamping plates and 4 mm socket terminals. It measures EMF without drawing current from the cell under test. Made by JLab in Ambala, India, it ships with a jockey.

Comparing EMFs and Internal Resistance
A steady driver cell and a rheostat send a constant current along the wires, so the potential falls uniformly with length. The cell under test is joined, through a galvanometer, between the starting end and the jockey; at the balance point no current flows through it, so the length gives its EMF rather than its terminal voltage. The driver EMF must be larger than any EMF being measured, and like terminals go to the same end of the wire.
Two cells compare as E1 / E2 = l1 / l2, switched in turn with a two-way key. Shunting the test cell with a known resistance R moves its balance from a length L to a shorter length S, and its internal resistance is r = R (L − S) / S.
Why Ten Wires
With the wires joined end to end, the total length is ten times that of a single-wire instrument, so the potential gradient is smaller and each centimetre stands for a finer step in voltage.
