Fruit Batteries

Fruit Batteries 

Materials 

• fruits or vegetables 
• metals 
• voltmeter 
• ammeter 

Purpose 

• The purpose of this experiment is to determine the electrical voltage output of different combinations of electrodes and fruits 
• It is also to find out which fruits give the highest voltage outputs 
• It is also to find out if the separation of the electrodes affects the voltage output 
• It is also to find out the voltages given off by different pairs of electrode materials 
• It is also to examines the voltage puts when the electrodes are connected in series and in parallel 
• It is also to find the amperage output of different pairs of electrodes 
• It will also examine whether the depth the electrode is inserted into the fruit affects either the voltage or amperage outputs 

Procedure 

Roll the fruit a little to make it a little juicier in the inside. Insert one electrode material into the juicy part of the fruit. Insert the second electrode into the juicy part of the fruit, but not so the two electrodes touch. 

Result 

1) Does the distance between the electrodes affect the voltage? 

 2) Does the distance between the electrodes affect the amperage?

 3)Does the type of fruit affect the voltage?

 4) Does the type of fruit affect the amperage?
