Chapter 6
Electrical energy
Overview
In this chapter, students will learn how to model the structure of the atom in terms of the nucleus, protons,
neutrons and electrons, describe factors that affect the transfer of energy through an electric circuit, look at
electrical safety features and evaluate claims relating to products such as electrical devices. They will be
able to describe how choices related to the use of fuels are influenced by environmental considerations and
discuss the impacts of the use of electrical energy on the environment including how scientific and
technological advances have minimised pollution from industry.
