Potentiometer Kit
Product Code : SCL-PL-11821
Potentiometer Kit (SKU SCL-PL-11821) brings together a potentiometer, a Daniell-type cell, a centre-zero galvanometer, a resistance box and meters for measuring EMF and internal resistance by the null method. It serves Class 12 physics practicals and B.Sc. electricity labs. Science Lab Supplies manufactures the kit in Saha, Ambala, India, at Plot 448 in the HSIIDC Industrial Area, and quotes it directly to schools, colleges, tender contractors and distributors.
Specifications
The kit is built around a 4-output potentiometer and a 30-0-30 galvanometer with 20 µA per division for detecting the balance point. A five-decade resistance box, a 22 Ω rheostat, a 1.5–12 V supply, a 0–10 A ammeter and a 0–5 V digital voltmeter complete the circuit.

Applications and Experiments for the Potentiometer Kit
A potentiometer measures EMF without drawing current from the cell at balance, which makes it more accurate than a voltmeter for this job. The kit covers the potentiometer experiments in the NCERT Class 12 physics practical syllabus and the matching B.Sc. and polytechnic electricity practicals.
- Class 12 physics: comparing the EMFs of two primary cells.
- Class 12 physics: internal resistance of a primary cell by potentiometer.
- B.Sc. practicals: calibrating a voltmeter or ammeter against the potentiometer.
Standard Scope of Supply
Each kit contains the potentiometer, Daniell-type cell, switches with the 22 Ω rheostat, 30-0-30 galvanometer, five-decade resistance box, 0–10 A ammeter, 1.5–12 V power source, 0–5 V digital voltmeter, twenty flexible leads, four U-shaped clamps and the two-way keys, enough for one practical bench.
Packing, MOQ and Lead Time
You may request a price for a single kit or enough for every Class 12 practical group. The quotation from Science Lab Supplies sets out packing, delivery time and price for that quantity, and a Wheatstone bridge or galvanometer kit can be added.
Science Lab Supplies, a registered exporter with an Importer-Exporter Code, is able to ship to buyers in Saudi Arabia, Oman, the Philippines, Nepal, Bangladesh and Zambia. Enquiries go through the contact page or the enquiry cart, and details for tender buyers sit on the lab tender page.
Frequently Asked Questions
What experiments does the Potentiometer Kit support?
It supports comparing the EMFs of two cells and finding the internal resistance of a primary cell, the two potentiometer experiments of Class 12 physics, plus meter calibration in college labs.
What galvanometer and resistance box are included?
The kit has a DC 30-0-30 galvanometer with 20 µA per division and a resistance box with five decades, from 10 x 0.1 Ω up to 10 x 1000 Ω.
Why does the kit include a Daniell cell?
A Daniell-type cell gives a steady EMF, so it can serve as one of the two cells whose EMFs are compared, or as the cell whose internal resistance is measured.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The kit leaves its own Saha, Ambala factory in India, and prices are given by the manufacturer directly rather than by a trading firm.
