Dear Jazmine,
Yes Lemon provide electricity
Reasons are;
Citric acid is provided by the lemon, and acids contain ions that conduct electricity, making the lemon an electrolyte.
When zinc is exposed to the acid in lemon juice, the acid oxidizes it, removing electrons.
The positively charged zinc ions that result move into the lemon juice, and the electrons that result collect in the zinc metal. They then rush across the wire into copper, which prefers electrons to zinc. Those electrons, now in the copper, draw a couple of protons or hydrogen ions from the acid and reduce them, adding electrons and producing hydrogen gas. We might be able to see very small bubbles of hydrogen gas forming on the copper electrode if we could see inside the lemon. To summarize, the electricity is generated not by the lemon itself, but by a chemical reaction caused by differences in electronegativities between zinc and copper.
