Product Description
Resistance Coil is a fundamental laboratory apparatus consisting of a wire coil made from materials with a known resistance, typically nichrome or similar alloys. It is widely used in physics and electrical engineering laboratories to study electrical resistance, heating effects, and circuit behavior. The coil’s wire length and thickness determine its resistance value, enabling controlled experiments involving Ohm’s Law, Joule heating, and energy dissipation. Resistance Coils are designed to withstand electrical current and heat without significant degradation, making them ideal for demonstrations, experiments, and calibration tasks in laboratory settings.
