ACKNOWLEDGEMENT
In preparing this thesis, I was in contact with many people, researchers,
academicians and practitioners. They have contributed towards my understanding and
thoughts. In particular, I wish to express my sincere appreciation to my supervisor,
Miss Rohana binti Abdul Karim., for encouragement, guidance, critics, friendship,
advice, information and motivation. Without their continued support and interest, this
thesis would not have been the same as presented here.
I am also indebted to University Malaysia Pahang for funding my degree
study. Librarians at UMP also deserve special thanks for their assistance in supplying
the relevant literatures and guiding me in using e-journal.
My sincere appreciation also extends to all my colleagues, ex-schoolmate and
others who have provided assistance at various occasions. Their views and tips are
useful indeed. Unfortunately, it is not possible to list all of them in this limited space.
I am grateful to all my family members especially my dad and mom for their moral
support, advice and understanding me.
Thank you.

ABSTRACT
With the technological demands of today, we must increase the number of
individuals that successfully complete a degree in science and engineering. To
accomplish this goal, the first obstacle to overcome is the year semester mathematical
calculating course. It has historically been a graveyard for students in engineering and
science. Multiuse Expert Electrical Calculator System designed as a system which has
many functions and also user friendly. This system is an expert system because by
using this system, we can show formula and also can analyze the calculation.
Calculator technologies nowadays not widely use because we cannot get the analysis
of the calculation after we get the result of calculation. Most of calculator cannot
appear circuit that we want to calculate and need a lot of time to get an accurate result
and make learning slower, difficult and not interesting. This system was designed by
using Visual Basic Language and window based to produce the calculator system and
for the learning purpose. Multiuse Expert Electrical Calculator System was covered
certain calculation in electrical such as Basic Circuit in Electrical and Robotics. So,
for all calculation, this system will show analysis to make users more understand
about the circuit connection in a short time. In order to make this system become user
friendly, the guidelines and more information about the topics will be inserted as a
learning purpose. This system built not only for student but it can be used by lecturers,
teachers, engineers and also non-technology person even they not familiar with
electrical calculations. So, this system will make a users find the accurate result
faster, easy and more interesting.

ABSTRAK
Permintaan teknologi hari ini membuatkan bilangan individu-individu yang
berjaya dalam bidang sains dan kejuruteraan mesti ditingkatkan. Untuk mencapai cita-
cita ini, halangan yang pertama untuk menyelesaikan masalah ini adalah bidang
pengiraan matematik. Secara sejarahnya, ia bagaikan perkuburan kepada pelajar-
pelajar yang berada dalam bidang sains dan kejuruteraan. Multiuse Expert Electrical
Calculator System dibuat sebagai satu sistem yang mempunyai pelbagai fungsi dan
senang digunakan. Sistem ini dikatakan expert kerana ia boleh menunjukkan formula
dan juga analisis untuk pengiraan. Teknologi kalkulator hari ini tidak digunakan
secara meluas kerana kita tidak boleh mendapatkan analisis untuk setiap pengiraan
selepas kita mendapat jawapan daripada pengiraan tersebut. Kebanyakan kalkulator
juga tidak dapat memaparkan litar dan memerlukan masa yang panjang untuk
mendapatkan jawapan yang tepat, serta membuatkan proses pembelajaran menjadi
lambat, susah dan tidak menarik. Sistem ini dibina menggunakan Visual Basic
Language dan window based untuk menghasilkan kalkulator sistem dan sebagai alat
bantuan pembelajaran. Multiuse Expert Electrical Calculator System meliputi litar-
litar asas dalam Elektrik dan Robot. Jadi, untuk semua pengiraan, sistem ini akan
memaparkan analisis bagi memudahkan pengguna lebih memahami tentang
sambungan litar dalam jangka masa yang pendek. Dalam proses menjadikan sistem ini
mudah digunakan, panduan pengguna dan maklumat-maklumat yang berkaitan dengan
tajuk disertakan. Sistem ini dibina bukan sahaja untuk pelajar, tetapi boleh juga
digunakan oleh pensyarah, guru-guru, jurutera-jurutera dan orang-orang yang diluar
bidang teknologi walaupun mereka tidak mahir dengan pengiraan elektrik. Jadi, sistem
ini akan menjadikan pengguna lebih mudah mendapatkan jawapan yang lebih tepat
dengan cepat, senang dan lebih menarik.
