Resistance Coil – 1 Ohm (KS4+)

The 1 Ohm Resistance Coil is a specialist, low‑resistance component designed for use in KS4 and post‑16 physics lessons. It allows students to introduce a very small, fixed resistance into electrical circuits, making it particularly useful for investigating high‑current behaviour and advanced electrical concepts in a controlled educational setting.

This resistance unit is housed in a durable block fitted with standard 4mm socket terminals, enabling quick, secure, and reliable connections using conventional laboratory leads. Compared with loose resistors or wire coils, these resistance blocks are safer, more robust, and far easier for students to use repeatedly during classroom experiments.

Rated at a nominal power of 1 watt, the 1 ohm resistance coil is suitable for low‑voltage educational circuits where current flow needs to be clearly observed and measured. Its stable, known resistance value ensures consistent results, helping students link theory to practical measurements with confidence.
