Can a lemon juice battery power a lamp?
« 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?

Try Googling  "Burrito Battery".
There ain'ta no sanity clause, and there ain'ta no centrifugal force Šther.
