Resistance Coil – 2 Ohm (KS4+)

The 2 Ohm Resistance Coil is a robust, low‑resistance component designed for use in KS4 and post‑16 physics laboratories. It provides a fixed, known resistance that can be easily added to electrical circuits, making it ideal for advanced basic electrical experiments where higher currents are required within controlled classroom conditions.

This resistance unit is mounted in a durable block fitted with standard 4mm socket terminals, allowing quick, safe, and secure connections using conventional laboratory leads. Compared with loose resistors, these resistance blocks are far more practical for teaching, offering improved durability, ease of handling, and faster circuit setup for students.

Rated at a nominal power of 1 watt, the 2 ohm resistance coil is suitable for low‑voltage educational circuits and demonstrations involving higher currents. Its stable, predictable resistance value supports accurate measurement and clear understanding of key electrical relationships.
