You are welcome!shoooooookriyaaa!

I also got 68 ohms but the current given is for 1.7 V, the circuit is of 9 V.by v=ir i get 68ohms
answer is 292. er says that most students forgot to subtract. subtract what?
I think I've got it,by v=ir i get 68ohms

i dint have a logic for my ans but now i got itI think I've got it,
The LED has a potential difference of 1.7 V,
The e.m.f. is 9 V,
The resistor hence has a potential difference of 9-1.7=7.3 V,
Minimum Resistance = 7.3/0.025 = 292 ohms.

The key again. I directly went to this part and did not even see the circuit diagram! READ QUESTIONS PROPERLY. Whoever said that was a genius.i can not believe how silly i m. i have no right to live in this planet any more
they gave p.d of lamp but i calculator R of resistor by p.d of lamp. much a silly mistake. my teacher would not even tell me answer but have murdered me.
Wow. You're brillianti dint have a logic for my ans but now i got it

Oh please.it was probably me who said it.
hmmm u're welcomeur logic is correct asma. we are calculating R of resistor not lamp. so we need to subtract to get p.d or resistor. thanx.
I NEVER get reversible equation...and then I stopped bothering because I didn't find any question on them. any important question regarding reversible reactions u have seen? and if u could please tell me what are the main points to be grasped in order to get hold of the topic :-/ and explain them a bit too like what is state of equilibrium n stuff and how will this knowledge be tested in the exam...
hydrogen burns, splint extinguishes and a pop sound is there.Yeah but from what I remember they also say that it is the hydrogen that pops not the splint :/ Or something like that So the word have to be really really clear :S
clash!If I'm not mistaken, then the answer is C. 32 g.
Let's just see what the answer is then.clash!
n whu turns out to be the BAAP!Let's just see what the answer is then.
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
