Zinc is the anode, and copper is the cathode.
The lemon flesh and juice provide the salt bridge and electrolyte solution.
Electrons flow from zinc to copper through the external wires.
Electrolytes flow in the lemon. Positive ions (cations) move toward copper electrodes (cathodes), and negative ions (anions) move toward zinc electrodes (anodes). These balance the charges building up.
Two cells in series provide more energy output than one. The clock may need more energy than can be supplied by one cell.
Batteries do not need external source of reactants, whereas a fuel cell must be supplied with reactants.

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
