Resistance in Series and Parallel Apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11187
The Lab Exports Resistance in Series and Parallel Apparatus features a heavy-duty, non-conductive insulated base panel with a clearly printed circuit schematic on its front surface. The board is populated with high-stability ceramic power resistors of known values to prevent resistance drift due to thermal heating during live tests. Connection points are designed as standard 4mm safety socket binding posts, allowing rapid, secure jumper wire connections without the need for soldering or complex breadboard wiring.
This didactic electrical board is designed to survive heavy, repetitive student handling in busy school laboratories. By arranging the physical layout to match standard textbook schematics, it eliminates student confusion and helps visualize current pathways. It functions as a foundational laboratory setup when coupled with external digital multimeters, DC power supplies, and connection patch cords.
Key Features
Vivid Schematic Printing: High-contrast surface silk-screening shows clear circuit pathways to aid student visualization.
Stable Power Resistors: High-wattage ceramic resistors ensure values remain consistent and do not drift with minor temperature increases.
Durable 4mm Terminals: Equipped with robust nickel-plated brass binding posts for stable low-contact resistance connections.
Shock-Resistant Base: Mounted on a rugged, non-conductive polymer or wooden base with non-slip feet for workbench safety.
No Assembly Required: Fully self-contained board design allows teachers to distribute the boards and begin laboratory sessions immediately.

Applications / Uses
Verifying the mathematical formula for series equivalent resistance: $R_{eq} = R_1 + R_2 + R_3$.
Verifying the mathematical formula for parallel equivalent resistance: $\frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_3}$.
Demonstrating current division in parallel branches and voltage division across series networks.
Integrating into introductory electricity modules within school science kits.
Serving as a practical testbed for teaching digital multimeter operations in ammeter and voltmeter configurations.
How to Use the Resistance in Series and Parallel Apparatus
Place the apparatus flat on a level, dry laboratory workbench.
Connect a low-voltage variable DC power supply to the main input terminals of the apparatus using insulated banana plug patch cords.
To test series circuits, use the patch cords to bridge the terminals such that the current has only one continuous path through the selected resistors.
To test parallel circuits, configure the jumpers so that the current splits across multiple parallel branches, returning to a common terminal.
Turn on the power supply, adjusting the output to a safe voltage level below the maximum rating.
Use an external digital multimeter to measure the current flowing into the circuit and the voltage dropped across each individual resistor.
Safety Note: Never exceed the maximum recommended input voltage or power dissipation limits, as overloading can overheat the internal resistors. Always switch off the power supply before modifying any jumper connections on the board.
Care & Maintenance
Store the apparatus in a dry, dust-free cabinet away from corrosive chemicals or acidic laboratory vapors to prevent terminal oxidation.
Clean the panel face using a dry, soft cloth; do not use heavy liquid solvents or abrasive scrubs that could fade the printed schematics.
Periodically inspect terminal posts to ensure the nuts remain tight and contact surfaces are clean.

Frequently Asked Questions
What is the Resistance in Series and Parallel Apparatus used for?
This apparatus is designed to help students physically set up circuits to prove equivalent resistance formulas and measure electrical characteristics like voltage drop and current divisions.
Do I need a separate power supply and multimeter to use this board?
Yes, this apparatus is a passive training board; it requires an external DC power supply, a digital multimeter, or separate voltmeters and ammeters to take physical measurements.
Can this board be used with high AC voltages?
No, this board is strictly designed for low-voltage, low-current DC electricity experiments (typically 0-12V DC) to ensure a completely safe classroom environment.
Why are ceramic resistors used instead of standard carbon film resistors?
Ceramic power resistors can handle significantly higher heat dissipation, ensuring the resistance value remains steady and the board is protected against accidental overcurrent situations.
Is this circuit board safe for middle school students?
Yes, when paired with a fuse-protected low-voltage DC power supply, the board presents zero electrical shock hazard, making it perfect for middle school through university level instruction.
