Apparatus for Studying Circuits for Series and Parallel Connections
Apparatus for Studying Circuits for Series and Parallel Connections (Product Code: SCL-359/021) is a demonstration circuit set used to compare how bulbs and cells behave when connected in series and in parallel, in school physics and general science lessons. Three bulbs, three 3–4.5 V batteries in their boxes and a 0–50 Ω rheostat let the teacher rebuild the circuit in front of the class. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Series and Parallel Circuit Apparatus Used For?
With three bulbs on hand, the difference between the two arrangements is easy to see. In series, the bulbs share the voltage, glow more dimly and all go out if one is removed; in parallel, each bulb receives the full battery voltage, glows brightly and keeps working when a neighbour is disconnected. Connecting the batteries themselves in series shows how cell voltages add, and the switch lets the class open and close the circuit cleanly each time.
The 0–50 Ω rheostat adds a variable resistance, so students can dim a bulb gradually and see how resistance limits current. Lay each circuit out clearly so the whole class can follow the connections, use the red and blue leads to keep the two sides of the supply distinct, and disconnect the batteries at the end of the lesson so they do not drain. As a physics demonstration kit for schools in India and abroad, it covers the circuit topics that come before formal Ohm's law work.
What to Specify When Ordering
- The number of sets needed for your classrooms.
- Whether spare bulbs or replacement batteries should be included.
- Extra 25 cm connecting leads if students will build circuits in groups.

Frequently Asked Questions
What does the series and parallel circuits apparatus include?
The Apparatus for Studying Circuits for Series and Parallel Connections (SCL-359/021) includes three 3–4.5 V batteries with boxes, three bulbs, 6 pairs of 25 cm red and blue connecting wires, a 36 V DC power switch, a 0–50 Ω rheostat rated 1.5 A, a magnetic table and a demonstration table.
What difference between series and parallel does it show?
With the Apparatus for Studying Circuits for Series and Parallel Connections (SCL-359/021), bulbs in series share the voltage, glow dimmer and all go out if one is removed, while bulbs in parallel each get the full voltage and stay lit independently.
What is the rheostat used for?
The 0–50 Ω rheostat, rated 1.5 A, in the Apparatus for Studying Circuits for Series and Parallel Connections (SCL-359/021) adds variable resistance to the circuit, so students can dim a bulb gradually and see how resistance controls the current.
Does the apparatus need a mains power supply?
No mains supply is listed for the Apparatus for Studying Circuits for Series and Parallel Connections (SCL-359/021); it runs from its three 3–4.5 V batteries in their boxes. Disconnect the batteries after each lesson so that they last longer.
Who manufactures the Apparatus for Studying Circuits for Series and Parallel Connections?
The Apparatus for Studying Circuits for Series and Parallel Connections (SCL-359/021) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations and spares come directly from the manufacturer.
Can the apparatus be ordered in bulk or exported?
Yes. The Apparatus for Studying Circuits for Series and Parallel Connections (SCL-359/021) is available in multi-set quantities for schools, colleges, dealers and importers in India and international markets. Send your quantity and destination through the contact page for a quotation.
