electricity

OpenStudy (somy):

i don't really get this q

OpenStudy (somy):

@thushananth01 @KissMyAxe

OpenStudy (somy):

can u please explain each point?

OpenStudy (anonymous):

use the formula R= pl/A Replace R with V/I ohms law than V/I= pl/A A is small therefore V must be large (inversely proportional)

OpenStudy (anonymous):

V = I R ---1 \[R = \frac{\rho l }{A}\]----2 Now see in eq 2, they are reducing the diameter, which means area is reduced, so since rho , l are constants and A is decreasing ,t the nResistance increases, now in eq 1, since current in constant, when u increse R , V would increase

OpenStudy (anonymous):

How many papers have u done somy?

OpenStudy (somy):

i did only may junes from 2008- now doin 2012

OpenStudy (somy):

hmmmm im trying to get u guys so i just use the resistivity formula

OpenStudy (somy):

?

OpenStudy (somy):

i think my brain is ready to burst im not getting this somehow how many papers did u do? @KissMyAxe

OpenStudy (anonymous):

The resistivity formula because they talked about diameters and length, not sure about any other formula which link these

OpenStudy (anonymous):

I did from 2002 to 2008. U can any question between these years :) Might not be able to answer some and before the exam i might do 2 papers :)

OpenStudy (anonymous):

What is it that u are not getting?

OpenStudy (somy):

>_< im scared really

OpenStudy (somy):

to be honest my brain switched off i guess i don't get a word

OpenStudy (anonymous):

U can ask :)

OpenStudy (somy):

okay let the question attack begin!

OpenStudy (anonymous):

I think I got it :o

OpenStudy (somy):

when i use resistivity formula, do i make Resistance as a subject?

OpenStudy (anonymous):

yes

OpenStudy (somy):

ok gimme a sec

OpenStudy (somy):

next what do i do

OpenStudy (anonymous):

Well u do know that resistance= V/I I have done many questions like these in maths! U know replacing the formulae etc this is the main Reason I find this easy

OpenStudy (anonymous):

exactly @somy its just mths

OpenStudy (somy):

i know @thushananth01 problem is im exhausted

OpenStudy (anonymous):

take a break :D

OpenStudy (anonymous):

Hey its okay if u do't do well this time U can give it again in Oct/Nov :)

OpenStudy (anonymous):

shuddupppp! @KissMyAxe

OpenStudy (anonymous):

OpenStudy (anonymous):

She will do great :)

OpenStudy (anonymous):

haha I'm glad I was able to explain Somy :)

OpenStudy (somy):

OpenStudy (somy):

unies here dont take first years in jan semester

OpenStudy (somy):

=_= i don't really feel like failing u see i'll be disappointed in myself >3<

OpenStudy (anonymous):

OpenStudy (somy):

lmao ur user name sounds so like http://www.youtube.com/watch?v=yFN1-uqt2WA&feature=kp

OpenStudy (somy):

i know math =_=

OpenStudy (anonymous):
