Applications and Experiments for the Junior Circuit Board
The board lets younger students wire a cell, switch, fuse and load into a working circuit and see the result straight away as a lit bulb or a turning fan. It is practical school physics lab equipment in India for the electricity chapters of Class 6 to Class 10 science.
- Class 6 science: building a simple closed circuit and seeing how the ON/OFF switch opens and closes it.
- Class 7 science: observing the effects of current with the bulb and fan, and the role of the fuse.
- Testing conductors and insulators by placing samples between two connectors in the circuit.
- Further circuit practice with separate items such as the Circuits Kit Cell Holder and the Circuit Switch.
Use cells giving 3 V in total, as stated, and never connect the board to mains or a higher-voltage supply.
Standard Scope of Supply
Each Junior Circuit Board is supplied with its transparent single-sided base carrying a cell holder, ON/OFF switch, connectors, fan, fuse and bulb holder. Cells and a bulb can be added to the quotation if your school needs them, along with any other circuit items.
Packing, MOQ and Lead Time
A quotation can be made for one board or for a class set so each student group has its own. Science Lab Supplies details the packing, delivery time and price for that number of boards, and senior boards or other circuit items can be included on the same quotation.
As an exporter registered with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Nepal, Bangladesh, Zambia, Rwanda, South Africa and Qatar. The business is registered under Udyam as a manufacturing enterprise (UDYAM-HR-01-0014546) and for GST (GSTIN 06ADEPJ0574F2ZU). Enquiries go through the contact page or the enquiry cart; the lab tender page covers tender procurement.
Frequently Asked Questions
What voltage does the Junior Circuit Board use?
It works on 3 volts DC, supplied through the cell holder on the board. Keep to this voltage and do not connect the board to mains power or a higher-voltage laboratory supply.
What components are on the board?
The board carries a cell holder, an ON/OFF switch, connectors, a fan, a fuse and a bulb holder, all on a transparent, single-sided plastic base, so students can follow the circuit layout as they work.
How is it different from the Senior Circuit Board?
The Senior Circuit Board also works on 3 V DC but adds a buzzer, rheostat, toggle switch and multimeter. The junior version keeps to the cell holder, ON/OFF switch, connectors, fan, fuse and bulb holder for first circuit lessons.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer, assembling the Junior Circuit Board at its factory in Saha, Ambala, India. Schools and distributors therefore receive their quotation directly from the maker.
