This Not to mention its clean energy. Save the earth and all that. -503 Weve had some students do this project and then try to use the lemon battery to light a small flashlights light bulb. The lemons did not work. Why? The reason is that the lemons produce only a very small current about one milliamp. This is not enough electric current to light the bulb. Even with multiple lemons, the amount of current flowing through the wire is not enough. Though the voltage is high enough 1.5 volts with two lemons, the current is too weak. But it was a great experiment! Even if an experiment doesnt work, it helps us to understand how things work. Good work!!!
