Principles of Lighting LK2285 Transformer Construction and Operation LK1989

This solution allows students to understand the principles of designing lighting systems for domestic and The Transformer construction and operation pack allows students to study not only how transformers work,
industrial buildings. The kit consists of a Locktronics base board, a set of high power MES LED bulbs, switches, but also study several different properties of induced magnetism. This kit consists of a plastic base, a laminated LOCKTRONICS
connectors and a light meter. Students can arrange the bulbs in varying positions and densities and measure iron core, mounting fixtures, and six coils protected in a heat resistant film. Topics covered include Lenz’ Law,
light intensity using the light meter provided. Students can explore the different effects on light intensity Faraday’s Law, how iron cores increase magnetic field strength, and electromagnetic induction itself. This
through the angle of lighting, the distance away from the light source, and the density of light sources. A full versatile piece of equipment can also be used to teach about how transformers used by power companies
