EBOOK - Electrical Circuit Theory and Technology 4th (John Bird)
EBOOK - Lý thuyết và công nghệ mạch điện (John Bird) - 735 Trang.
‘Electrical Circuit Theory and Technology 4th Edition’ provides coverage for a wide range of courses that contain electrical principles, circuit theory and technology in their syllabuses, from introductory to degree level.
New topicsincluded in this edition include resistor construction and colour code, more information on batteries, dangers of constant high current with insulation, loading effect of instruments, earth point and causes of short circuits,potentiometers and rheostats, and rectifier smoothing. In addition, freely available on the website are 10 straightforwardlaboratory experimentswhich may be downloaded and edited.
