Product Code : SCL-EAE-12035

The Ohms Law Kit with Built-in Power Supply is a self-contained electrical training apparatus used for demonstrating the mathematical relationship between voltage, current, and resistance in educational physics labs. Designed for secondary students and engineering classrooms, it simplifies circuit verification without external power sources.

Product Description

The Ohms Law Kit with Built-in Power Supply by Science Lab Supplies provides an exceptionally reliable platform for exploring fundamental electrical principles. The apparatus features a regulated, short-circuit-proof variable DC power source alongside highly accurate measuring instruments. Encased in a rugged, impact-resistant ABS plastic enclosure, this workbench trainer ensures exceptional durability under intensive laboratory environments.

Every trainer board is engineered with an explicit, easy-to-follow schematic diagram printed directly onto the durable composite front panel. The panel houses high-precision analog dual-range voltmeters and ammeters, multiple fixed-value wire-wound resistors, and heavy-duty 4mm shrouded safety sockets. It serves as an essential instructional aid for schools and technical colleges aiming to expand their inventory of high-quality scientific laboratory instruments.

How to Use the Ohms Law Kit with Built-in Power Supply

1. Position the main console unit securely onto a level, dry laboratory workbench.
2. Ensure the variable DC voltage knob is turned fully counterclockwise to the zero position before turning on the device.
3. Connect the integrated ammeter, voltmeter, and chosen onboard test resistor using the provided 4mm banana plug patch cords to complete the series-parallel circuit loop.
4. Plug the AC power cord into a standard mains wall socket and flip the primary power toggle switch to the ON position.
5. Rotate the variable voltage control knob clockwise slowly, recording the subsequent current increases at regular voltage intervals to verify the formula $V = I \times R$.

Handling Note: Always switch off the primary power toggle and return the voltage dial to zero before altering the patch cord connections to protect the internal analog meter needles from sudden high-voltage deflections.

Care & Maintenance

• Panel Cleaning: Clean the acrylic meter faces and composite front panel periodically using a soft, dry lint-free microfiber cloth.
• Liquid Precautions: Keep the apparatus completely isolated from moisture, damp environments, or open chemical stations inside the physics laboratory.
• Storage Environment: Store the unit inside a clean, dry equipment cupboard away from direct localized heat sources to prevent electronic component degradation.
