A2 physics ultimate paractical revision

thx sooo much!!

...but i can't read them. can you shrink me into a fruitfly?

I dont have a scanner so I had to take a photo of the pages. I had to compress it a lot, so the quality is rubbish, but you can just about read the text.

My teacher has strongly suggested we shouldnt spend too much time on logaritms(another hint?), but told us to look at the specimen paper(found on the edexcel website).

well when you save them resize them,they wont fit normally here,go to picture or tools resize,depends on the program ur using!

we were told that the CROs are essentially voltmeters therefore can measure voltage. does it say that in the book?

i tried that...but the resolution is not big enough for the words to be read when i enlarge the pics...

(i'm sorry for being such an annoying little bugger ;_

I'm sorry I cant help you then the forum doesn't allow pics larger than 100 kb

They measure voltage and can also measure it with respect to time, so they can plot a graph on the screen of voltage against time in the case of an a.c. supply.

by adjusting the time base and using the grid on the screen you can determine the frequency of the supply

Can anyone tell me about the exam format please?

it's alright. i don't want to bug you too much anyway.

if you can email it to me [email protected] i'd be really grateful, but don't bother if you have to spend a lot of extra time on it. it's the thought that counts anyway.

I'd have tro scan them all over again but I googled this for you it's pretty much the same

im doing my exams on 28th, but im from sri lanka. i dread the 5A paper more than the 3A paper, what i hate most is the theory questions i mean the calculations are ok. are those Qs like why is graphical representation inaccurate(?) ? or stuff like that repetative in papers??

i was talkin to my teacha today and he said that this years practical wont require us to set up any equipment jst 2 get results .....so i'd say luk ova mark schemes and see how marks are awarded for taking results e.g. tabulating etc...
