since I dont have the paper, but the numbers are quite in this form, yeah it was around 10-9.

ok ... if u find the rite answer temme k?

okay

No he is not. That is a serious 2014 paper. All of the IGCSE papers have been leaked in Kuwait, and multiple variants have been changed. You can see in the background; the paper seal, the folder in which the papers come. Also the paper quality is exactly the same as the paper that comes in the exam. This my friends, is a real 2014 paper that, that person has in his possession

i thought the same n so asked hm , anyways forget thx nw

is monochromatic light :-
light of one colour??

Alternating current in primary coil produces changing magnetic field in soft iron core. This induces an a.c. in the secondary coil.
If step-up, no. of turns in 2ndary coil greater; output voltage greater. And vice-versa.

What about reducing heat losses... Power, current and resistance k baarey mein throw some light na.

cn sme1 plz explain me relationship btwn resiistence , voltage and current

 

[Gamedos]

Can anyone explain to me how the AC generator works???

 

[hard_worker]

cn sme1 plz explain me relationship btwn resiistence , voltage and current

R=V/I
as I increases R decreases
if V increases R increases

Can anyone explain to me how the AC generator works???

first u should know that in a generator the KE applied to coil generates current....
so as the coil is rotated current is generated which is detected by a sensitive ammeter.

 

[hard_worker]

Its 2014 paper

R u series or just or WHAT ?

 

[Gamedos]

R u series or just or WHAT ?

yes they are serious
it is the 2014 may/june paper 1

 

[Phoenix Blood]

cn sme1 plz explain me relationship btwn resiistence , voltage and current

V=IR

V increases, R increases, as long as current is constant, and vice versa.
V increases, I increases, as long as resistance is constant, and vice versa.
I increases, R decreases, as long as voltage is constant, and vice versa.

 

[Phoenix Blood]

yes they are serious
it is the 2014 may/june paper 1

For which subject????????

And who's leakin' it?

 

[hard_worker]

yes they are serious
it is the 2014 may/june paper 1

But How ! thts impossible ... guys this year were screwed the curve is gonna be as high.. many cheating we might even have to repeat the session!!! PLEASE STOP IT ! y not study and do ur best instead of wasting time leaking papers

 

[Gamedos]

And who's leakin' it?

ive got no idea but they say it was leaked in kuwait

because some people got the exam and it wont be a fair cmpetition
