Senior Circuit Board

Product Code : LSK-EAE-11121

Senior Circuit Board (SKU LSK-EAE-11121) is a single-sided student circuit board that works on 3 V DC and carries a buzzer, rheostat, fan, toggle switch, bulb holder, fuse and a multimeter, so learners can build circuits and measure them on one board. It is meant for school laboratories teaching the basics of electricity and electronics. Science Lab Supplies makes it at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and its factory quotes schools, colleges, tender contractors and distributors directly.

Specifications

The table below gives every listed detail. Briefly, it is a single-sided board for 3 volts DC with a cell holder, toggle switch, connectors and fuse, three loads (bulb holder, buzzer and fan), a rheostat to vary the current, and a multimeter for taking readings during school experiments.

Applications and Experiments for the Senior Circuit Board

Because the board combines loads, a rheostat and a multimeter, students can move from simply lighting a bulb to measuring how current and voltage change in a circuit. It suits the electricity chapters of Class 8 to Class 10 science and makes useful physics lab equipment in India for lower secondary benches.

• Class 10 science: changing the current with the rheostat and reading the multimeter to relate current and voltage.
• Comparing loads: seeing how the bulb, buzzer and fan respond as the rheostat is adjusted.
• Circuit safety: discussing how the fuse protects the circuit and how the toggle switch controls it.
• Extension work with a Rheostat Circuits Kit panel or an extra Circuits Kit Bulb Holder for series and parallel layouts.

Keep the supply at 3 V DC, set the multimeter to the correct range before switching on, and switch off before changing connections.

Standard Scope of Supply

The Senior Circuit Board is supplied as one single-sided board fitted with a cell holder, buzzer, rheostat, fan, fuse, connectors, toggle switch, bulb holder and a multimeter. Cells can be listed on the quotation, along with any spare circuit components the class will need.

Packing, MOQ and Lead Time

Request a price for a single board or for enough boards to give every student group its own. Each quotation from Science Lab Supplies sets out packing, delivery time and price for the chosen quantity, and junior boards or extra meters can be quoted alongside.

Science Lab Supplies, an Importer-Exporter Code holder, can ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. To place an enquiry, go to the contact page or use the enquiry cart; buyers working to a tender can see the lab tender page.

Frequently Asked Questions

Does the Senior Circuit Board include a meter?
Yes. A multimeter is part of the board, so students can take readings while they build circuits with the buzzer, rheostat, fan and bulb holder, without a separate meter for basic work.

What voltage does it use?
The board works on 3 volts DC through its cell holder. Do not connect it to mains or to a laboratory supply set above 3 V, because it is designed for 3 V DC operation only.

How does it differ from the Junior Circuit Board?
The Junior Circuit Board has a transparent plastic base with a cell holder, ON/OFF switch, connectors, fan, fuse and bulb holder. The senior board adds a buzzer, a rheostat, a toggle switch and a multimeter for measurement work.

Is Science Lab Supplies the manufacturer or a trader?
It is the manufacturer, not a trader. The Senior Circuit Board is produced at the Science Lab Supplies factory in Saha, Ambala, India, which prepares and sends every quotation for it.
