Question

Does the metals determine how high or low voltage is in fruit battery?
Or is it the pH level in fruits that determines voltage? also can you give a source to this.

Answer 1

Answer: 1.788 volts.

Explanation:

To solve this problem we can combine battery cells to create higher voltages. Building more lemon batteries and connecting them with a metal wire from "+" to "-" adds the voltage from each cell. The two lemon batteries above, combine to produce a voltage of 1.788 volts.
