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??

yah it is

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

 

[Gamedos]

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

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

Hard worker, eh?
... One sec, how CAN they LEAK the paper? It'll be of another variant, if so. And what in the WIDE cosmos is wrong in seeing another variants' papers?

Yes but this paper one is my varient lucky me
