Product Code : SCL-EAE-14618
Indian Lab Suppliers supplies the Potentiometer Apparatus (Product ID: 14618) as part of its electrical and electronics range. It measures EMF and potential difference by the null method, drawing no current from the cell at balance.
Quick Answer
A uniform constantan or manganin wire carries a steady current, creating a constant potential gradient along it. A jockey is moved along a millimetre-graduated scale until the galvanometer reads zero, and the balancing length gives the EMF. It is made either as a 1–1.5 m slide-wire or as a multi-wire board, on a wooden or powder-coated metal base, so please confirm the type at quotation.

Where This Is Used
It is used to compare EMFs, find the internal resistance of a cell and calibrate low-voltage meters. Test cells such as the Daniell Cell (Product ID: 14620) or Leclanche Cell 1.5V (Product ID: 14619); see also the Potentiometer with Jockey Pencil (Product ID: 10799).
