Hello all,
I am just a guy playing around. I was trying to see if I understood correctly what electrolytes were, so I set out to make a simple "battery" out of saltwater. It has been done before many times and I thought I could at least make it light an LED.
Here it is :

The problem is that despite the fact that I managed to reach 4.75Volts of voltage I can't make the LED light up.
To be precise , whenever I make contact and close the circuit it lights up for an instant and then the light dies out. If I repeat .. the same happens each time. That is the reason I am writting this topic too. I would like to ask anyone who might know why it does not function as I thought it would be? I am trying to understand physics just as a hobby so please go easy on me if I said something really stupid in this post. :)
Thanks in advance for any comments ,

P.S. : Also another question, I read something about amperage but from wikipedia I deduced it is the same as current? Is that correct? Also ... unfortunately my internal fuse has been broken in the multimeter and I can't measure current :(
