Apparatus for Studying Circuits for Series and Parallel Connections
Product Code : SCL-PL-11827
Apparatus for Studying Circuits for Series and Parallel Connections (SKU SCL-PL-11827) is a magnetic-board circuit set with three bulbs, three cells in holders, a switch and a 0–50 Ω rheostat, used to compare series and parallel wiring by bulb brightness. It suits middle-school science and Class 10 electricity lessons. Made by Science Lab Supplies in its Ambala plant at Plot 448, HSIIDC Industrial Area, Saha, India, the set is manufactured there and quoted straight to schools, colleges, tender contractors and distributors.
Specifications
The series-and-parallel set is described part by part in the table that follows. In short, circuits are built on a magnetic board from three 3–4.5 V cells in their boxes, three bulbs and six pairs of 25 cm leads, switched by a 36 V, 0–3 A DC switch and controlled by a 0–50 Ω, 1.5 A rheostat.

Applications and Experiments for the Series and Parallel Circuit Apparatus
Students can wire the bulbs first in series and then in parallel and compare brightness, see what happens when one bulb is removed, and dim a bulb with the rheostat. The set supports electric-circuit topics in CBSE/NCERT Class 6 science and series and parallel combinations in Class 10.
- Class 6 science: a simple closed circuit with a cell, switch and bulb.
- Class 10 science: bulbs in series and in parallel, and why house wiring is parallel.
- Adding cells in series to raise the voltage across the bulbs.
- Controlling current and brightness with the rheostat.
Standard Scope of Supply
The apparatus comes with three 3–4.5 V cells in their boxes, three bulbs, six pairs of 25 cm red and blue 4 mm leads, a DC power switch, the 0–50 Ω rheostat and the magnetic board. Meters for measuring current and voltage can be added on the quotation.
Packing, MOQ and Lead Time
Ask for a single set for teacher demonstration or one for every student group in the class. The quotation you receive states the packing, delivery time and price for that quantity, and a multimeter or the resistance-factors apparatus can be quoted alongside.
Science Lab Supplies is a registered exporter with an Importer-Exporter Code, so it can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia.

Frequently Asked Questions
What can students learn with the series and parallel apparatus?
They can see that bulbs in series share the voltage and all go out if one is removed, while bulbs in parallel each get the full voltage and keep working independently.
Can meters be added for measured readings?
Yes. Bulb brightness shows the effect of each arrangement, and for numerical readings an Ammeter reading 0–10 A and a Voltmeter reading 0–20 V DC can be added to the same quotation.
Is Science Lab Supplies the manufacturer or a trader?
This magnetic-board circuit set leaves the Science Lab Supplies plant in Saha, Ambala, India, as a manufactured product of the company, and the price on your quotation is set there without a dealer in the chain.
