AI Customer ServiceWhen you place your hands on the metal plates of a hand battery, your skin and the metals create a battery. This is the basis of how a hand battery functions.
Another way to test the battery is with a voltage meter or multimeter. Note that U.S. pennies made before 1982 are 95% copper, but newer pennies only have a 2.5% copper coating. For further experimentation, compare the electric current when you make a battery using only older pennies and one using only newer pennies.
A firm handshake can transfer twice the number of microbes as a gentle one, affecting microbes transfer. The same phenomenon applies when you firmly grip door handles or other surfaces. Make sure you wash your hands with soap and water after grabbing something that might not be clean.
1. Make your battery by stacking 12 ‘cells’ against each other, each cell made up of one penny, one wet paper towel circle, and one foil circle in that order. 2. Wrap an 8-10′ piece of insulated wire with stripped ends around the battery once and twist the ends together against the battery so that the wire holds the cells together. 3.
