EBOOK - Kỹ thuật và nguyên lý điện & điện tử 3th - Tác giả: John Bird (422 Trang).

Electrical and Electronic Principles and Technology, 3rd Editionintroduces the principles which describe the operation of d.c. and a.c. circuits, covering both steady and transient states, and applies these principles to filter networks, operational amplifiers, three-phase supplies, transformers, d.c. machines and three-phase induction motors.
New topicsincluded in this edition are a complete update on semiconductor diodes and transistors, and additional material on batteries, fuel cells and alternative and renewable energies, relative and absolute voltages, self and mutual inductance, virtual test and measuring instruments. In addition, applications in all areas are expanded and emphasised and some new further problems added.
A new feature of this third edition is that afree Internet download(lecturers only) is available of asample of solutions(some 400) of the 530 further problems contained in the book — see below.
Another new feature is afree Internet download (available for lecturers only) of all 517 illustrations contained in the text — see below.
