ahh i see now.. thanks alot mate
This is wat i did:
P=I^2R but then i said 2(0.05/2.50)+0.02/4.7 =0.04

then 0.04*100=4%

Just so you know, it is 2% of 4.7 which is 0.094. So, if you wanna actually use the fractional way to do it is :

2(0.05/2.50) + 0.094/4.7 = 0.06

0.06 x 100 = 6% :)

Careless you! To use 0.02/4.7!

I always think that tuition's a waste of time and money :( I rather use that time and money to learn something else such as singing! :D

Singing...? Ok i guess thats one way to use money :). Tutors are not bad if you really don't understand something but most of the times you understand what you are doing a lot better if you try to figure it out yourself ;)
My advice for the day haha ;D

How did you guys find the physics paper 1, easy, medium, hard, made rocket science look easy? I personally found the question paper to be more difficult than the past papers that i've done but some of the questions were really easy like the ones at the end.

I'm sure you're pretty smart yourself and the paper was not TOO hard but still hard and tricky.

@Tyserius

Why is it 2% of 4.7 ohms?

The reading given in the question is 4.7+- 2% ??

I guess its too early to discuss about the paper itself but i want to discuss it once we are allowed, some of the questions i wasn' t very sure of when i shaded in the box...but in the end i kind of don't want to discuss it as well because its over and done with... man i'm confused... ??? i don't know what i want to do haha...
