Resistance Coil – 100 Ohm (KS4+)

The 100 Ohm Resistance Coil is a robust and reliable circuit component designed for KS4 and post‑16 physics education. It provides a simple and effective way to introduce a known resistance into electrical circuits, making it ideal for a wide range of basic electrical experiments in school laboratories.

Unlike loose resistors, this resistance coil is housed in a durable block fitted with standard 4mm socket terminals. This allows quick, safe, and secure connection using conventional laboratory leads, making circuit construction easier and more reliable for students working in pairs or small groups.

Rated at a nominal power of 1 watt, the 100 ohm resistance coil is well suited to low‑voltage educational circuits. It offers stable and predictable performance, helping students achieve consistent results when measuring current, voltage, and resistance during practical investigations.
