Product Code : EL-SLE-5801
Jlab Export is a leading Circuit Board Manufacturer,and suppliers in India

Circuit Board (code EL-SLE-5801) is a circuit-building kit for school electricity lessons: a base board with holes for making connections, 12 plain connectors, nine lamp holders and a rheostat mounted on connectors, two push switches, ten 1.25 V lamps, three reels of wire and a set of materials to test. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

Specifications

How Does It Compare with Other JLab Circuit Boards?

Choose this kit when you want a single kit that covers lamps, switching, resistance, conduction tests and a simple electromagnet with every part itemised. The Worcester board suits teachers who prefer connection pillars and flexible clip strips, and the student board is a simpler demonstration option.

What Is the Circuit Board Used For?

Students lay out a circuit on the board with the plain connectors and the mounted parts, then change it one step at a time — adding lamps in series or in parallel, closing a push switch, or adjusting the rheostat to dim a lamp. The bare eureka and copper wires let them compare a resistance wire with a good conductor; the pencil leads, steel wool and copper foil can be tested to see which materials conduct; the plastic-covered copper wire wound on a soft iron nail makes a simple electromagnet; and the rectifier shows that current passes through it in one direction only. These activities follow the electricity chapters of CBSE and state-board science from class 6 to class 10, which makes the kit a practical electricity experiment kit for school labs, science clubs and teacher-training sessions.

Cells or a power supply are not among the listed contents, so plan a low-voltage source that suits the 1.25 V lamps, and ask JLab if you would like advice with the quote. After each lesson, wind the bare wires back on their reels, keep the lamps and small parts together, and replace any lamp that has failed before the next class.

What to Specify When Ordering

• Number of kits — the minimum order is 10 kits; schools usually plan one kit for each student group.
• Power source — cells or a supply are not part of the listed contents; say what you will use, or ask JLab to suggest one.
• Spare lamps and wire — lamps, bare wire and steel wool are used up over time; ask whether spares can be quoted with the kits.
• Meters — for measuring current and voltage, add an ammeter and voltmeter as separate items in the same enquiry.

Frequently Asked Questions

What does the Circuit Board kit contain?
A base board with holes, 12 plain connectors, 9 lamp holders and a rheostat mounted on connectors, 2 mounted push switches, 10 lamps of 1.25 V, crocodile connectors, clips and leads, reels of bare copper, bare eureka and plastic-covered copper wire, a 150 mm square of copper foil, a resistor, a rectifier, 2 soft iron nails, steel wool, 4 pencil leads and a hardboard disc.

Which experiments can students do with it?
Series and parallel lamp circuits, switching, controlling brightness with the rheostat, comparing resistance wire with copper wire, testing which materials conduct, making an electromagnet with a nail and covered wire, and showing one-way conduction through the rectifier.

Are cells or a power supply included?
No power source is listed among the contents. Plan a low-voltage source suited to the 1.25 V lamps; JLab can advise when it quotes.

What is eureka wire?
Eureka is a copper–nickel resistance alloy of the constantan type, whose resistance changes very little as it warms. Bare eureka wire is used where a steady resistance is needed, which makes it a good contrast with the bare copper wire in the kit.

How many lamps are supplied?
Ten lamps rated 1.25 V are listed, for the nine lamp holders on connectors.

How does it differ from the Worcester Circuit Board?
This kit builds circuits from connectors placed on a base board with holes and itemises every component and test material. The Worcester board, listed separately, uses terminals, metal connection pillars and clips on flexible strips with its own accessory units.

Who manufactures this circuit board kit?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and quotes for it as the manufacturer.

OEM Manufacturer

JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian maker of school science and physics lab equipment, incorporated in 2017 with its base on Hargolal Road, Ambala, Haryana. The circuit board kits are assembled at JLab’s own works rather than bought from a trader, which means schools, colleges, dealers and importers order factory-direct, each kit is checked by eye before packing, and repeat orders and replacement parts are handled by the people who make them. JLab exports worldwide and ships to buyers in every region — for example Ghana in West Africa, France in Western Europe, Tajikistan in Central Asia, Mexico in North America and Hungary in Eastern Europe. School tenders are covered on the JLab lab tenders page.

Parts and Meters for Electricity Lessons

• Rheostat — an 11 ohm, 3 A single-tube rheostat for circuits that need finer current control.
• Crocodile Clips — spare spring-loaded clips in black and red for colour-coded connections.
• Bulb Holder — a regular holder for torch bulbs when extra lamp positions are needed.
• Connecting Wires — double-cotton-covered copper wire for further connections and coils.
• Ammeter — a desk-stand meter for measuring the current in the circuits students build.
