Leclanche Cell Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12427
Jlab Export is a leading Leclanche Cell Manufacturer,and suppliers in India
Leclanche Cell (code EL-PL-12427) is a wet primary cell for physics practicals, made up of a zinc rod 12.5 mm in diameter and a charged porous pot 150 mm high and 60 mm across, each with a terminal, giving an EMF of about 1.4 V. It is one of the two cells whose EMFs students compare on a potentiometer. Both the rod and the pot are made by JLab in Ambala, India.

Where the 1.4 V Comes From
The zinc rod is the negative electrode: in the ammonium chloride electrolyte it is oxidised to zinc ions, releasing electrons into the external circuit. In a Leclanche cell the positive electrode is the carbon inside the porous pot, packed round with manganese dioxide, which acts as the depolariser by oxidising the hydrogen that would otherwise collect on the carbon. That reaction is slow, so under a steady load the cell polarises: its terminal voltage sags, then recovers after a rest. It suits circuits that draw current in short bursts, or hardly at all.
Comparing EMFs on a Potentiometer
At the balance point a potentiometer draws no current from the cell under test, so polarisation does not disturb the reading and the full EMF is measured. Balance the Leclanche cell and then a Daniell cell against the same steady current in the potentiometer wire: the EMFs are in the ratio of the balancing lengths, E1/E2 = l1/l2. With about 1.4 V against the Daniell cell’s 1.1 V, the Leclanche cell balances at the longer length.
