I am a full time specialist Physics tutor operating in Klang Valley. I've been educating student for more than 10 years. My specialty is to transform student that had failed their physics subject into a better result. Even some of them managed to get an A in their final exam, You can read their testimony in this blog. I provide home tuition for physics subject to those living nearby KL especially around W.Maju, Ampang,Melawati and Setiawangsa. At the same time i 'm giving online tuition to all malaysia & overseas student. For tuition centre looking for a physics tutor, i'm also able to give seminar and conduct weekly classes. Meanwhile,for school teachers who are organising physics seminar, i am happy to assist u in that aspect. If u have enquiry on my service, do contact or whatsap me at 017-2877589 or email me at celikfizik @ gmail . com

SPM 2009 : Welcome to Electricity


Dear all..now I’ll be discussing the next chapter Eleccity. B4 I go further, please bear in mind, in form 5, 3 out of the 5 topics comes from a word ElecTRO (electricity,electromagnet, electronics)

Electricity is the fundamentals..u really need to understand tis chapter coz its basic shall be applied in next 2 chapters..lets go deeper


2.1 Analysing Electric fields & Charge flow..

In this subtopic u must be able to:


1. Relate between electron (charge) flow & current:

How??? The flow of electrical charges produces electric current

So what does it mean by electrical charges?

In electrical current, the electrical charges are flowing electrons (-ve charged).

Thus the relationship is ..:If electrons are flowing, current will be flowing as well!

(Note:Check your reference book..refer details on Van Der Graff)


2. The next outcome..u must know how to define Current.
What is current?
Current is the rate of flow of charge
By formula: I = Q/t

I = current , unit is ampere(A)
Q =charge, unit is coulomb (C )
t = time taken (s)


3. Describe an electric field??


  • an electric field is a region in which an electric charge experiences a force.
  • lines of electric field moves away from + ve charge
  • lines of electric field points towards - ve charge.

4. U must also know how to sketch the electric lines with correct direction:

5. U also need to describe the effect of electric field :
Watch these video..then refer yr reference book..or text book(pg46)

well..do u think u cn read everything in the book within a month?? So the best way study the facts by doing quest...to get A u need to b realistic

joey said...

i m ur mother oso.. noob la u .

Wonder said...

anybody know anything about application question section b&c.....the question sure is tricky like the best design for a submarine or how to turn normal thermometer to lab thermometer

mya said...

teacher...please teach me how to make a good physics essay...im really weak in paper 2 section B and C..

I'm really weak in this subject. I only got 8E in my exam..My SPM is next year but I really worried to face this paper with result like this. Our physics teacher always busy and there is no tuition class around (@ Kundasang). Its really hard for me to understand it by myself. Shall I change school or...??? hmm what should I do? help me T_T

cikgufizik said...

myra..trust me,u r lucky to realise all these at this stage. Its not too late,U still hv 1 more yearr to turn things to be much better.Think positive.there must be a way to solve yr prblems. If ur teacher is too bz, find othr teacher..& ask their help. U kena buat muka tembok sikit ;) .. study grp with yr friends can be helpfull as well. If u need to learn fizik, keep coming to tis site nxt yr :)

excuse me ,
how can i understand physic subject easily?? especially te concept.. is there any tips ...

cikgufizik said...

pls check "revisit myphysics study tips" section in the frnt page..i've discussed lots of tips on how to study physics
