Brightsparks 100R Resistor Module – ST019

The Brightsparks 100R Resistor Module (ST019) is a durable, education‑grade circuit component designed specifically for use with the BrightSparks 4Kids Electricity Kits. Enclosed in a strong sealed ABS plastic housing, this module contains a 100Ω, 3W metal oxide resistor with a 5% tolerance, making it perfect for investigating resistance, current limiting, and voltage behaviour in low‑voltage circuits.

Designed for safe use in 1.5–6V DC circuits, the module features two unpolarised 4mm plug‑in sockets for easy connection with standard laboratory leads. Its non‑slip rubber feet provide stability during experiments, while its fully RoHS‑compliant construction ensures suitability for classroom environments.

As with all Brightsparks modules, this unit is intended solely for low‑voltage battery use and should never be connected to mains electricity under any circumstances.
