Electrical Principles 8e has been revised to underpin the UEE30820 Certificate III in Electrotechnology Electrician qualification. Written to AQF level 3, this edition has been strengthened to align to the new units of competency, and further address new emerging technologies. Additional chapters make the text also usable for UEE22020 Certificate II in Electrotechnology (Career Start), broadening the appeal and giving students the opportunity to carry the same text through two qualifications.
