Applications and Experiments for the Potentiometer
A potentiometer measures potential difference by balancing it against a steady fall of potential, drawing no current at balance. That makes it essential school physics lab equipment in India for Class 12 practicals that compare the EMFs of two cells or find the internal resistance of a cell.
- Class 12 physics: comparing the EMFs of two primary cells, such as a Daniel Cell and a dry cell.
- Class 12 physics: determining the internal resistance of a cell using a shunt resistance.
- Detecting balance with a centre-zero Galvanometer in series with the jockey.
- B.Sc. labs: calibrating a voltmeter or ammeter, with the driving current set through a rheostat.
Standard Scope of Supply
The potentiometer is supplied as one unit: the wooden base with its brass blocks and 4 mm socket terminals, the 100 cm wooden scale and a knife edge jockey. Cells, a galvanometer, a rheostat, a key and connecting leads are not included and can be quoted separately.
Packing, MOQ and Lead Time
We can quote for one potentiometer or for a set covering every group in a Class 12 practical. The Science Lab Supplies quotation shows packing, delivery time and price for the quantity you name, and the cells, galvanometer and rheostat for the circuit can be added to it.

Frequently Asked Questions
What comes with the potentiometer?
It comes with a knife edge jockey. The unit itself is a wooden base with brass blocks, 4 mm socket terminals and a 100 cm wooden scale; cells, a galvanometer, a rheostat and leads are ordered separately.
Which experiments is it used for?
It is used to compare the EMFs of two cells, to find the internal resistance of a cell and, in college labs, to calibrate meters. Each of these relies on finding a balance point read on the 100 cm scale.
Do the 4 mm sockets suit standard leads?
The brass blocks are fitted with 4 mm socket terminals, which take 4 mm plug leads. Check the plug size of your existing leads before ordering, or ask for leads on the same quotation.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies makes this potentiometer in its own factory in Saha, Ambala, India. You therefore receive the quotation from the manufacturer itself, not from a dealer or trading company.
