Demountable Transformer Coil – 100 Turns, 2A, 0.55Ω [0578]

The 100‑Turn Transformer Coil is a robust, low‑resistance coil designed for use in school physics laboratories with demountable transformer systems. Suitable for KS4 and above, this coil is ideal for demonstrating key concepts in electromagnetic induction, alternating current, and transformer theory.

Wound with 100 turns of insulated wire, the coil is rated at 2 amps and has a very low resistance of just 0.55 ohms. This makes it particularly suitable for experiments involving high current and low voltage, allowing students to clearly observe the effects of changing turn numbers on transformer output and efficiency.

Designed for repeated classroom use, the coil is easy to mount and interchange with other coils, supporting flexible experimental setups and clear comparison between different transformer configurations.
