Electricity is used in a wide range of applications, such as manufacturing, healthcare, transport and entertainment. All of these are reliant on electrical technology in one form or another. For example, for someone to be able to visit a holiday destination, go to a music festival or download the latest track by their favourite performer, numerous electrical activities and concepts must be coordinated.
Electrical technology provides the link between science and its application. It is underpinned by a range of enabling technologies and concepts such as materials science, energy efficiency, environmental impact, geological characteristics and design.
This unit provides an introduction to ways in which electricity is produced, the options we have about how and why we produce it, and the disposal of related by-products. The unit considers how the electricity that has been produced is then moved to where the customer (end-user) needs it. It also examines the materials used and whether alternatives exist or could be found.
On completion of this unit a learner should:
- Know the methods used to produce electrical energy
- Understand the properties and applications of conductors, insulators and magnetic materials
- Understand the physical arrangements of supply, transmission and distribution equipment
- Understand how electrical energy is used to support applications of electrical technology.
