How many volts can a lime produce?

Answer 1

The voltage an electrochemical cell produces does not depend on the electrolyte (e.g. type of fruit), it depends on the two electrodes (e.g. metal strips).

The voltage is determined by the relative electronegativities of the two electrodes. For example all cells using a copper electrode and a zinc electrode will produce the same voltage, regardless of the kind of electrolyte they are put into.

Another example all cells using a carbon electrode and a zinc electrode produce 1.5 volts, regardless of whether the electrolyte is acidic (the original dry cell batteries), basic (modern alkaline batteries), or neutral (a salt).

Answer 2

usually .5 volts!
