Resistance Coil – 5 Ohm (KS4+)

The 5 Ohm Resistance Coil is a robust, classroom‑ready component designed specifically for KS4 and post‑16 physics education. It provides a low, fixed resistance that can be easily introduced into electrical circuits, making it ideal for a wide range of basic electrical experiments and investigations in school laboratories.

Housed in a durable block with standard 4mm socket connections, this resistance coil allows quick, secure, and reliable circuit assembly using conventional laboratory leads. Compared with loose resistors, these resistance units are safer, more practical, and better suited to repeated use by students working independently or in groups.

With a nominal power rating of 1 watt, the 5 ohm resistance coil is ideal for low‑voltage educational circuits where higher currents can be explored safely. The stable resistance value ensures consistent, repeatable results, supporting clear understanding of the relationship between current, voltage, resistance, and power.
