What is the Cosine Rule for Lighting? How to Calculate Light Levels at an Angle from the Source
In this video we look at how to calculate light levels at a point that is not directly below the light source. We look at the cosine rule for illuminance or lighting, it involves knowing the angle from the light source to surface and how this fits in with the inverse square law. These videos are designed to help learners who are studying any kind of electrical course including City and Guilds 2365, 5357 and 8202 as well as the EAL Diploma in Electrical Installation. #joerobinsontraining #Electricaltrainingvideos #scienceandprinciples
