The book starts with the basics of alternating current, how it is generated, and how it differs from direct current. It then guides you through the practical tools engineers use, including vector and graphical representations, to illuminate key ideas such as phase differences, sine waves, and power relationships. Although the text is non‑mathematical in tone, it builds a solid grounding for anyone working with polyphase systems, from students to practicing engineers.

Focuses on a non‑mathematical, visual approach to complex ideas
Introduces generation, representation, and basic principles of alternating currents
Explains vectors, phase differences, and practical power considerations in polyphase work
Aimed at readers transitioning from direct current to alternating currents and polyphase schemes

Ideal for readers of engineering texts who need a solid, approachable foundation in polyphase currents without getting bogged down in heavy equations.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
