Understanding the principle of operation, you can find a way to make a simple battery yourself . Here are some small suggestions for you. Although the battery is only enough to light a small LED bulb, it certainly makes you feel interesting and surprised.
- Some coins
- Silver paper
Cardboard paper (cardboard paper)
- Vinegar to eat
Cut coin-sized cardboard pieces
Cut foil into pieces similar to carton paper
Soak the carton in the tissue so that it evenly covers all sides of the paper
Proceed in order of coins - vinegar paper - foil. The more the quantity, the greater the power of the battery
Through the ammeter, we can see that "battery" has appeared amperage
Lets test the results together. The battery is quite low, so it can only light the LED bulb low or enough to run the clock.
To increase efficiency, make more batteries and directly circuit them together.
If the amount of battery is enough, you will be able to charge the phone as well
