im just starting science and we were doing an experiment measuring the voltage from fruit with an voltmeter we were using
copper and zinc
to stick in the fruit,
in a series circuit the v-meter only had 2 wires connected one with the zinc in the negative and copper in positive i held the copper in my right hand and the zinc in my left and i got a reading of 0.62v my friend got 0.58v and another got 0.59v
i dont under stand how this works so what im seeing here is if you were to connect maby 3-5 people in this circuit you could light a small bulb
if so then that means we could charge some thing or make something big work with a lot of people conected
p.s i found that it was highest at my hands, elbow was 0.27v face was 0.24
diddent try the feet
