Science and Principles Level 2
This is the page for the slightly more advanced material that you need to pass your Level 2 exams. We delve a little more deeply into the murky world of electrical science and discuss some slightly more advanced concepts.
What is electricity?
This video will start you on your journey to understanding the most basic question an electrician must answer: What is electricity?
Videos are training aids for City and Guilds 5357, 2365 and EAL Diploma in Electrical Installation Levels 1, 2 and 3.
What are the basic components of a circuit?
Almost every circuit installed will have the components featured in this video and you'll need to be able to identify them. Watch the video to check your understanding.
