This time I tried to post something about Lime Battery. First
I was curious and then I bought some lime in a shop in the market complex. The
price is cheap Rp 1000 each piece. Then I use a copper and nails which
previously used to arrange a potato battery.
Finally, the results are surprising. 4 pieces potato
and 4 Cups salt water usually only
produces a voltage about 2.8 volts. But the 4 pieces of lemon can produce voltages up
to 4 volts.
One thing I don’t understand is, when the battery is loaded
LED, a third type of battery voltage drop to around 1.8 Volt.
I have not tried
further to find the reason.
