KIR: Lemon Battery

What is the main purpose of a lemon battery experiment

• To generate electricity using fruits

• To conduct a chemical reaction for lighting a bulb

• To test the pH level of the lemon

In the lemon battery experiment, what role does the lemon play?

• It acts as a conductor of electricity

• It provides the necessary chemical reaction for producing electricity

• It insulates the wires

What is the role of the copper and magnesium in the lemon battery?

• Copper provides the necessary acid for the reaction

• Magnesium releases electrons, creating an electric current

• Copper absorbs hydrogen gas to complete the circuit

• Magnesium dissolves and powers the battery directly

To increase the voltage in a lemon battery setup, what can you do

• Use a larger lemon

• Increase the number of lemons connected in series

• Use a thinner copper wire

Why do electrons flow in the lemon battery setup?

• The lemon juice attracts electrons

• The lemon juice has a high concentration of positive ions

• Copper and magnesium have different electron affinities

• The wire becomes magnetized and pushes electrons
