Title: Can a lemon juice battery power a lamp?
Post by: thedoc on 15/06/2012 06:30:03

bradley Vandermerwe  asked the Naked Scientists:
   
I am doing a science experiment on making batteries out of household appliances. From using 225ml of vinegar and 75ml of lemon juice as my electrolyte and connecting these batteries in series I managed to obtain a voltage of 2,72 volts. This was enough to power a small clock.

However when i connected these batteries to a 3 watt 1,5 volt light bulb the bulb did not light up.

Now I would like to know why this is?

Your help would be much appreciated.

Regards Brad

What do you think?
