BrightSparks Variable Resistor Module 100 Ohm 5W [2559]

The BrightSparks 100 Ohm Variable Resistor Module is a robust, classroom‑friendly component designed for use with the BrightSparks 4Kids modular electronics range. This adjustable resistor allows students to vary resistance smoothly within a circuit, making it ideal for clearly demonstrating how resistance affects current, voltage, and component behaviour.

Designed for safe operation in 1.5–6V DC circuits, the module features a 100 Ω, 5 W variable resistor suitable for repeated educational use. Electrical connections are made using two unpolarised 4mm plug‑in sockets, enabling quick, intuitive, and error‑free setup with standard BrightSparks leads.

For added stability during experiments, the module includes non‑slip rubber feet, keeping it firmly in place on benches and desks. Its durable construction ensures reliable performance in busy primary and secondary classrooms.
