Unit 3
Manufacturing and Industry
Task for students
You are going to study a text about
electrical engineering. While studying,
take notes of important information
about electrical engineering. After the
study, you’ll answer some review
questions without referring to the text
again.
Electrical engineering -- Definition
Electrical engineering — sometimes
referred to as electrical and electronic
engineering — is an engineering field
that deals with the study and
application of electricity, electronics
and electromagnetism(电磁). The field
first became an identifiable(可以确认
的) occupation in the late nineteenth
Electrical engineering--Coverage
century after commercialization(商业
化) of the electric telegraph(电报) and
electrical power supply(电力供应).
The field now covers a range of substudies including power, electronics,
control systems, signal processing(信
号处理) and telecommunications(远程
通讯).
Electrical engineering -- Distinction
with electronic engineering
Electrical engineering may or may not
encompass(包含) electronic
engineering. Where a distinction(区别)
is made, usually outside of the United
States, electrical engineering is
considered to deal with the problems
associated with large-scale
Electrical engineering -- Distinction
with electronic engineering
electrical systems
such as power
transmission(传输)
and motor control(电机
的控制), whereas
electronic engineering
deals with the study of
small-scale electronic
systems including
computers and
integrated circuits.
Electrical engineering -- Distinction
with electronic engineering
Another way of looking at the
distinction is that electrical engineers
are usually concerned with using
electricity to transmit energy, while
electronic engineers are concerned
with using electricity to transmit
information.
Electrical engineering
--Complex electronic circuits
Electronic
engineering deals
with the study of
small-scale
electronic systems
including
computers and
integrated circuits.
Electricity is used
to transmit
information.
Education in electrical
engineering
Education
Electrical engineers typically possess
an academic degree with a major in
electrical engineering. The length of
study for such a degree is usually four
or five years and the completed
degree may be designated as a
Bachelor of Engineering, Bachelor of
Education in electrical
engineering
Science, Bachelor of Technology or
Bachelor of Applied Science
depending upon the university. The
degree generally includes units
covering physics, mathematics,
computer science, project
management and specific topics in
electrical engineering. Initially such
Education in electrical
engineering
topics cover most, if not all, of the subdisciplines of electrical engineering.
Students then choose to specialize in one
or more sub-disciplines towards the end of
the degree.
Some electrical engineers also choose to
pursue a postgraduate degree such as a
Master of Engineering/Master of Science
(MEng/MSc), a Master of Engineering
Management, a Doctor of Philosophy (PhD)
in Engineering, an Engineering Doctorate
Education in electrical
engineering
(EngD), or an Engineer‘s degree. The
Master and Engineer’s degree may consist
of either research, coursework or a mixture
of the two. The Doctor of Philosophy and
Engineering Doctorate degrees consist of a
significant research component and are
often viewed as the entry point to
academia(学术界). In the United Kingdom
and various other European countries, the
Master of Engineering is often considered
an undergraduate degree of slightly longer
duration than the Bachelor of Engineering.
