light r bulb same power taken
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.
the Sparks on the copper makes the wire on the light bulb makes the 9v light bulb turn on.
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.
