In this video I go through a typical exam question that you may come across and go through the answer step by step, this process combines information from previous videos including the inverse square law, the cosine rule, Pythagoras' Theorem and trigonometry.
This video is designed to help anyone studying electrical science especially the City and Guilds 2365, 5357 and 8202 as well as the EAL Diploma in Electrical Installation.
