How electricity works working principle

Electricity and the science behind it can be tricky, especially because you can’t see it – all you can do is see the effects of it or feel it. In this chapter you will investigate some of the basic scientific principles of electricity, and the applications and uses that are fundamental to a technician’s role in the building services engineering industry. This chapter is broken down into logical sections to enable you to grasp the science and progress on to the Level 3 science syllabus. You will be introduced to the basic concepts followed by worked examples, backed up by a range of practice questions at different levels. The order of the learning outcomes has been changed slightly from the C&G specification in some instances: this is to allow a logical build-up of knowledge before you progress to the next subject.

In this video, we are going to be looking at how electricity works.

Now, this is pretty essential knowledge for any engineering, so we’ll run through the basic parts of what you need to know.

Everything, including you, is made from atoms. All the materials we use are made from atoms.

The materials are just different because the construction of their atoms are slightly different.

The atoms are made from three particles, two of which are found inside the nucleus and the third particle sits outside this.
