Digital Ohms Law Apparatus 5 watts

Product Code : SCL-EAE-12053

Digital Ohms Law Apparatus 5 watts (SKU SCL-EAE-12053) is a bench experiment for verifying Ohm's law, V = IR, by measuring voltage across and current through a known 100 Ω, 5 W resistance. Students, teachers and laboratory instructors use it for measurement, calculation, graph plotting and demonstrations in basic electricity. Science Lab Supplies manufactures the apparatus at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and its factory supplies schools, colleges, tender contractors and distributors directly.

Specifications

The specification table below lists every documented detail. In short, the apparatus pairs a 100 Ω resistance rated at 5 W with a 0–10 V DC voltmeter range and a 100 mA ammeter range, wired through 4 mm banana terminals and supplied with patch cords and an instruction manual.

Applications and Experiments for the Digital Ohms Law Apparatus

Students apply a range of DC voltages, record matching current readings, calculate R = V/I and plot a V–I graph to show the straight-line relationship. It fits the Ohm's law experiment in Class 10 science and Class 12 physics, as well as basic electricity units in diploma, ITI and vocational courses.

• Class 10 and Class 12 practicals: studying how current through the resistor changes with potential difference, using an Electronics Lab Battery Eliminator 2A as the DC source.
• Varying the current in steps with a Rheostat, Constantine (Eureka) Wire connected in series.
• Comparing results with the self-powered Ohms Law kit Apparatus, which has its own variable supply.
• Introducing electrical measurement and simple circuit analysis in technical training.

Never exceed the 5 W rating or the 10 V and 100 mA ranges, and switch off before changing any connection.

Standard Scope of Supply

Each delivery includes one Digital Ohms Law Apparatus 5 watts, a set of patch cords and an instruction manual. A DC power source is not part of the standard set; a suitable supply, extra leads or other accessories can be added to the quotation if the laboratory needs them.

Packing, MOQ and Lead Time

Ask for a quotation for one apparatus or for enough units to give every group in a physics practical its own set. Science Lab Supplies quotes the packing, delivery time and price for that quantity, and supplies or rheostats from its school physics lab equipment in India can share the quotation.

Thanks to its Importer-Exporter Code, Science Lab Supplies can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Get in touch via the contact page, send a list through the enquiry cart, or check the lab tender page for tender buying.

Frequently Asked Questions

What resistance does the apparatus use?
It uses a 100 Ω resistance rated at 5 W. With the 0–10 V DC voltmeter range, the current stays within the 100 mA ammeter range, so readings remain on scale throughout the experiment.

Can students plot a V-I graph with it?
Yes. Students record several pairs of voltage and current readings, plot voltage against current and confirm that the slope of the straight line equals the 100 Ω resistance.

Is the meter display digital or analogue?
The exact meter configuration of the unit being supplied is confirmed on the quotation, so please state your preference when you contact us. The resistance, ranges and terminals remain as listed above.

Does Science Lab Supplies make this apparatus?
Yes, it is made in-house. Science Lab Supplies, a science apparatus manufacturer in India, assembles the apparatus at its Ambala factory, and colleges and distributors receive quotations directly from that factory.
