How much current flows through the battery compared with the lightbulb?

More.
Less.
The same amount.
No current flows through the battery.

hartnn · Answer

it cannot be more or less, due to conservation

hartnn · Answer

and since current flows inside the battery too, 
it should be same amount

anonymous · Answer

this seems like a trick question ahah why do they do this

hartnn · Answer

so that you think :)
the more you think, the more clear are your concepts!

anonymous · Answer

ahah im scared to put it in

hartnn · Answer

nevermind.
try it
do you get more than 1 chance ?

anonymous · Answer

ahah I mean Im scared to plug in the answer, all our work is done online

anonymous · Answer

no I get one to answer it and if I get it wrong I get 50% taken off

anonymous · Answer

let me look at my book and see if I find anything

hartnn · Answer

if i were you, i would have gone for same amount.
but let me browse internet to make sure...

anonymous · Answer

okay thank you very much =)

hartnn · Answer

yes, current flows inside the battery too.

hartnn · Answer

pretty, now i am pretty sure its the same amount.

anonymous · Answer

I think you are right but i dont know why I feel like it would be more

anonymous · Answer

this is what my friend told me A light bulb is made out of tungsten, tungsten has a a very high resistance with current and thus generates a lot of friction, generating more heat and light energy, that's why you see the light and feel the heat when you touch a bulb.

A battery has little or no resistance, and thus I believe more current flows through the battery than through the bulb.

he thinks its more, ahhh lol

nvm he looked at this after http://answers.yahoo.com/question/index?qid=20080415125833AAB6QBm

ganeshie8 · Answer

generally speaking its same amount, 

to be precise, there will me some leakage current that flows thru battery always no matter what. if u consider that also, then the answer will be more current.

but id tick 'same current'.. .

anonymous · Answer

okay thank you very much!

ganeshie8 · Answer

total current =  current thru light buld + current directly thru battery


current directly thru battery is negligible usually. so tick 'same amount'... 
i may curse us if u get 50% off lol... really its a trick question, depends on who asks the question.. .

ganeshie8 · Answer

*u may..

anonymous · Answer

that was correct! you guys are awesome! 
thank you very much =D

phew!
