I thought the salt bridge was used to separate the anode and cathode so they could be in different chemical environments. In that case the lemon is not a salt bridge since the anode and cathode are in the SAME solution.

I am demoing a lemon battery made with a copper sheet electrode and a galvanized nail for the Zn electrode. I get a voltage of 0.954 volts from the battery which slowly decays over time. Why is my voltage this close to the 1.1 V expected value if my concentrations of copper and zinc ions are...
