You would need two sets of electrodes made from two different metals, preferably from opposite ends of the Periodic Table. You put the electrodes out from each other on the top of the lemon. Then you would connect the lemons together in series, alternating the metals you use. For instance, you would connect the copper electrode of one lemon to the zinc electrode on the next lemon. You might need 6-9 lemons, depending on the voltage. You might do better to use a LED instead of a regular bulb, since they draw less current. You can test your lemon cells using a voltmeter to get the polarity and the amount of voltage.
the Sparks on the copper makes the wire on the light bulb makes the 9v light bulb turn on.
A lemon can power a light bulb because of the acid in it. The acid is used as a conductor and powers the lemon.
it depends on the amount of acid in the lemon and lemon does not create make it conducts electricity
A lemon can power up a light bulb by acting as an electrolyte in a chemical reaction with the metals in the light bulb. When zinc and copper electrodes are placed in the lemon, a chemical reaction creates an electrical current that can power a small LED light bulb.
The hypothesis regarding using a lemon to power a light bulb would be that the acidic juice of the lemon can act as an electrolyte to facilitate a chemical reaction with the metal electrodes of the light bulb, generating enough electricity to produce light.
lemon can power a light bulb b'coz lemon contains citric acid which can serve as an electrolyte if the connections r complete it undergoes elecrolysis & sets up an electrolytic cell.
A lemon can act as a battery due to its citric acid content reacting with the metal electrodes in the light bulb. The electrolytes in the lemon facilitate a flow of electrons, creating a small electric current that can light up the bulb.

The citric acid inside in a fruit could make it work. Fruits that is part of the citrus family has a contains a citric acid. For example a lemon, it could make a light bulb work. :)
