i just saw tht on yahoo ans.....its for same resisitance i guess....
but still if its a potential devider or sumthing only one thing will effect....

If you provide enough wattage it will be bright.
V = IR, P = IV so all are connected.

for the whole question.........plx plx tell quickly....

answer this too....

Question batao??

 

[peacce]

180N --> 30cm
800N--> x
x= 133

isi link ka Q.6 part Biii??? muhammadali233

 

[Laibaaa]

Question batao??

So as stupid as it sounds, whats the relation between voltage and current ._. explain please

hahahahhahh poocha q phrrrrrrrrr

 

[Asad rehman]

EMF is simply work done on the charge.
Potential difference is work done by charge when it passes between two points,
Current is f;ow of electric charges,and volts is work done on these charges volt=W/Q.
hope this will help.

cos Im a stupid person who should've studied physics before.

Voltage is directly proportional to current if resistance is kept constant according to OHMS LAW
Voltage*Current= Watts

Yeah but like what happens to voltage if current increases and vice versa?

part B ??????????? muhammadali233

 

[Laibaaa]

Voltage is directly proportional to current if resistance is kept constant according to OHMS LAW
Voltage*Current= Watts

And what if resistance isn't constant?

 

[peacce]

answer kro mri queries koi

Are you prepared for tomorrow?i don't think so
Cause this is fundamental/basic of electricity but no problem with that, Voltage=Current x Resistence
If the Current is Increased the resistance decreases and vice versa there is no direct (such) relation between voltage and Current as it acts as a constant rather than a proptoion or inverse

farmaiyn!?!

 

[Ram97]

And what if resistance isn't constant?

If voltage and resistance increase current decreases or vice versa
