This edition guides you through the core ideas of alternating quantities, how they repeat over time, and how to measure their key values. It explains concepts like the crest, mean, and virtual values, and shows why the virtual value is handy for practical instruments.

From simple harmonic motion to three-phase systems, you’ll see how engineers analyze transformers, motors, and generators. The text also covers how losses, regulation, and short-circuit behavior are studied in real machines, with practical approaches to testing and interpretation.

Foundations of periodic time, frequency, and the cycle of values
How maximum, mean, and virtual values relate in practical circuits
Introduction to three-phase, star and mesh (delta) connections
Methods for measuring losses, regulation, and short-circuit behavior

Ideal for readers seeking a solid, hands-on understanding of alternating currents and their applications in electrical engineering.

Store Description

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 visit 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.
