Can Electrical Current Flow Through Fruit?Experiment by Ted
Cruz
Purpose1 To find out if a fruit can conduct electricity.2 What
type of fruit is the most conductive?Research1 I searched Google to
find similar experiments.2 I watched Youtube to learn about voltage
and electrical current.Design1 Use the same power source and
voltage.2 Use wire of equal length and gauge.3 Use only fruits.4
Use fruits of the same size and weight.
HypothesisIf a current of twelve volts is passed through a
fruit, I believe that enough voltage will be left to light a four
volt L.E.D. bulb. I also think that an orange will allow the most
current to pass through, giving off the most amount of
light.Procedure1 Turn off power supply.2 Insert probes into the
fruit.3 Turn on power supply.4 Check L.E.D. for brightness.5 Record
voltage drop from multimeter.Materials List1 Apple 2 Orange 3
Tomato4 Multimeter5 Eight one point five volt batteries.6 Battery
container.7 Wire of equal length and gauge.8 Electrical
tape.ConclusionThe experiment was a success. All the fruits tested
carried an electrical current. The apple was the most conductive
not the orange. I was surprised that the orange was the least
conductive fruit. All of the fruits tested were able to power the
L.E.D.ChartFuture ConsiderationsIf I were to do the experiment
again I would vary the voltage and use fruit juice for a more
controlled experiment. It is possible that the outcome could be
different.AppleL.E.D
