Hi there, my name is John Kelly. I am Lecturer in Electrical Engineering.Are you looking to gain an understanding of alternating current? Perhaps you are looking to pursue a career in Electrical Engineering, or your studying to become an Electrician. Whether your pursuing a career or strengthening your knowledge, this course is for you.This course is for beginners. You do not need any previous knowledge of Alternating Current. We will start right at the beginning and work our way through step by step.There are exercise files available to download so that you can practice your newly acquired skills as you progress through the course.By the end of the course you will be confident working with values such as reactance and impedance. You will be able to recognise how power is used in AC circuits, the effects of power factor, and power factor correction.So join me on this course and together we will explore the fundamental knowledge that is vital in understanding how Electricity, and Electrical systems behave.This course will be useful if you are studying for an Electrical Science exam, or to be an Electrician, an Engineer, or wish to go on to study at a higher level.
