Why Electrical Engineering?Admin BitsCircuit basics

TODAYTODAY’’S AGENDAS AGENDA Why Electrical Engineering?

• How much do we rely on Electrical Systems?

• What would the world be like if all electrical systems suddenly stopped working?

2

Why do you do this subject?• Electrical systems are an integral part of many

modern systems.

• Why Electrical??????– Many advances in electrical and electronic systems

eg computers and semiconductor systems.– Small, light weight.– Lot of computing power– Reliability– Flexibility

Lots of things need electricity and hence ELECTRICAL ENGINEERS.

Summary of Lecture ProgramAdmin bits

• Notes etc on web site:– Use link ELEC1111 - Electrical and

Telecommunications Engineering after you log on to:

http://vista.elearning.unsw.edu.au/– important messages posted. – download lecture notes, lab notes, tutorial

handouts and other course-related materials– marks

Weekly noticeThings to do in Week 1: • Read all the Course Info handout.• Try out the web site• Have you done the safety lecture and

filled out the declaration form?– If not then purchase the safety video $4 at school of EE&T.

Watch the video.– Read Safety manual available from lab staff EE G14B– Sign declaration form and hand in to me or give it to the

school office marked to my attention.

• Buy the Laboratory kit

Weekly noticeBuy the Laboratory kit –

COMPULSORY:$10 - soldering and components kit.$5 – Safety Goggles (or bring your own)

OPTIONS:Pay extra $10 – Lab Experimental notes or download them from the web print them and bring them along to each week.Pay extra $15 for a prototyping board (Useful if you are going on in EE & T)

Pay $ at School Office in Elec. Eng. Building (room EEG1) for lab manual, soldering and components kit.

Get receipt, pick up goods from the Electronic Workshop (room EEG14B)
