Electricity Demonstration Kit, 24-Piece — Magnetic, Whiteboard-Mounting || 28-

This 24-piece magnetic electricity demonstration kit provides a highly visible, hands-on system for teaching fundamental concepts in electricity and electric circuits. Each major component features a strong magnetic backing, allowing complete circuits to be assembled directly on a standard magnetic whiteboard for clear viewing during classroom demonstrations.

The kit includes digital voltage and current meters, fixed and variable resistors, resistance wires, switches, lamp holders, bulbs, battery holders, and connecting modules. Components can be combined to demonstrate and investigate series and parallel circuits, voltage, current, resistance, Ohm’s law, electrical switching, resistance of different conductors, and other introductory electricity concepts.

Bright LED displays on the voltmeter and ammeter make measurements easy to read during demonstrations. Forty connecting leads in multiple lengths provide flexibility when constructing circuits, while the included hinged carrying case keeps the complete system organized for storage and transport.

Kit Includes

• 1 digital voltmeter with bright LED display — 0–20 V range, 0.1 V resolution

• 1 digital ammeter with LED display — 0–5 A range, 0.01 A resolution

• 2 AA battery-holder modules — accommodate up to 8 AA cells connected in series for a 12 V supply

• 5 fixed-resistor modules — values include 5 Ω, 10 Ω, 15 Ω, and 20 Ω

• 1 sliding rheostat — variable resistance, 0–20 Ω

• 3 resistance-wire types — 3 m nichrome, 1.5 m copper, and 1.5 m iron

• 3 SPST switches — single-pole, single-throw

• 2 SPDT switches — single-pole, double-throw

• 2 square lamp holders for E10 miniature screw-base lamps

• 6 connecting modules with binding posts

• 8 miniature lamps — 4 × 3.8 V and 4 × 6 V

• 40 connecting leads with spade terminals — assorted 12, 25, 40, and 60 cm lengths

• 1 hinged plastic carrying case

The magnetic component design makes this kit particularly effective for teacher-led demonstrations, allowing students throughout the classroom to clearly see circuit layouts, connections, and meter readings.
