Applications and Experiments for the 12V 2A Battery Eliminator
The eliminator supplies steady practical power for circuit experiments that would otherwise drain cells: Ohm's law, series and parallel resistors, lamps, coils, meters and switches. It fits school physics lab equipment in India from Class 10 upwards, college electricity practicals and basic electronics benches in vocational institutes.
- Class 10 science (Electricity): verifying Ohm's law and comparing series and parallel resistors, with current read on the LCD Display Digital Ammeter.
- Class 12 physics: powering current-electricity practicals on the Meter Bridge or Wheatstone Bridge With Pencil Jockey, with current set by a Rheostat, Constantine (Eureka) Wire.
- B.Sc. and diploma electricity labs: a reusable source for meters, coils and resistance boxes.
- ITI and vocational electronics training: powering lamp, switch and trainer-board circuits during supervised assembly.
Wire circuits with the unit switched off, check polarity for DC work, never short the terminals and stay within the 12 V, 2 A rating, under supervision.
Standard Scope of Supply
Each order line covers one AC/DC Battery Eliminator 12V 2A main unit as described above. Leads and other accessories for the model you choose are listed on the quotation, and circuit components such as meters, rheostats, plug keys and resistance boxes are quoted as separate items.
Packing, MOQ and Lead Time
A quotation can cover one eliminator for a demonstration bench or enough units for every student group in an electricity lab. As a science apparatus manufacturer in India, Science Lab Supplies sets out packing, delivery time and price for that quantity, and meters or rheostats can share the same quote.
With an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Send your list through the contact page, collect items in the enquiry cart, or use the lab tender page for tender work.
Frequently Asked Questions
What does 12V 2A mean on this eliminator?
It means the unit is rated at 12 volts and can deliver up to 2 amperes, about 24 watts in all. Keep the total current drawn by the lamps, coils and resistors in your circuit within that 2 A rating.
Can it replace dry cells in school practicals?
Yes. It runs from the laboratory mains, so repeated Ohm's law, lamp and meter experiments can continue through the day without buying and changing cells, provided each circuit is designed for a 12 V, 2 A source.
Does it give both AC and DC output?
The model is designated AC/DC. The output arrangement, terminals and any protection features of the unit you order are stated on the quotation, so tell us whether your experiments need AC, DC or both.
Is Science Lab Supplies the manufacturer or a trader?
It is the manufacturer. The eliminator is built at the Science Lab Supplies works in Saha, Ambala, India, so your quotation is issued by the maker itself rather than by a reseller or trading agent.
