Demountable Transformer Accessory Set No. 1 – High‑Current Demonstrations [0492]

The Demountable Transformer Accessory Set No. 1 is a specialist physics teaching resource designed to demonstrate the powerful effects of step‑down transformers operating at high current and low voltage. Suitable for KS4, GCSE, and A‑Level physics, this set provides dramatic, memorable demonstrations of electrical energy transfer.

When used with a compatible demountable transformer system and a mains coil (required, not included), this accessory set clearly shows that step‑down transformers can deliver currents large enough to heat conductors, boil water, or even weld thin metal wires. These striking effects help students understand why transformers are essential in both domestic applications and industrial power systems.

The set is designed for robust classroom use and allows teachers to safely demonstrate how decreasing voltage results in a corresponding increase in current, reinforcing the fundamental transformer relationships between voltage, current, and power.
