Resistance Coil – 200 Ohm (KS4+)

The 200 Ohm Resistance Coil is a practical and robust component designed for use in KS4 and above physics lessons. These resistance units provide a convenient and reliable way to introduce fixed resistance into electrical circuits, making them ideal for classroom experiments and demonstrations.

Housed in a durable block with standard 4mm socket terminals, the resistance coil allows quick, secure connections using conventional laboratory leads. This design offers a safer and more user‑friendly alternative to loose resistors, particularly in busy teaching environments where ease of setup and clear visibility are important.

Rated at a nominal power of 1 watt, the 200 ohm resistance coil is well suited to low‑voltage educational circuits. It provides stable and predictable resistance, helping students obtain consistent results when investigating electrical principles such as current, voltage, resistance, and power.
