# Electric Current and Current Flow

TEACHER: Mrs. Russo

I. Statement of Purpose and Hypothesis:

Our purpose for this project was to find out what fruits and

vegetables could generate an electric charge. We also wanted

to find out which ones had the greatest and least charge. Our

hypothesis stated that the potato would have the greatest

charge.

II. Methodology:

The materials we used for this project were the fruits and

vegetables and an amp meter to measure the current flow in

them. We learned the difference between electrical charge and

conductivity. We measured the electrical charge first and the

conductivity second. First, we looked for current flow in each

of the fruits and vegetables using the micro amp scale on the

meter. Second, we measured resistance in each of the fruits

and vegetables using the ohms scale on the meter. For the

second procedure, we took measurements in the fruit or

vegetable with the probes both close together and far apart,

because we wanted to find out how much the resistance increases

as you move them farther apart. Finally, we graphed and

charted our findings.

III. Analysis of Data:

The fruit or vegetable that had the strongest current flow was

definitely the lemon with 2 micro amps. The least was the red

potato with 0 micro amps. In terms of the resistance measured

in ohms, the potato had the highest resistance rating with the

probes close together...
