How is potato a good conductor of electricity?

Any substance conducts electricity because of the presence of ions or free electrons. The motion of these ions and electrons causes the flow of electricity.
The potato itself has a mixture of starches and salts and some water. The presence of salt and water releases ions, which result in the conduction of electricity. Thus, potato conducts electricity.
You will study about ions in higher grades.

as it is having a watery substance when we cut it .... that water can conduct electricity very well.....

The potato itself has a mixture of starches and salts and some water. A salt, like table salt, in water releases ions. Ions are atoms that have an electrical charge. Table salt releases two electrically charged ions - a sodium ion with a positive charge, and a chlorine ion with a negative charge.

HI RUMI.

HERE IS YOUR ANSWER

HOPE THIS HELPS YOU ,,,,,,,

BECAUSE POTATO CONTAINS  watery substance and starches.

AND I THINK YOU MIGHT BE  KNOWN TO THESE SUBSTANCES.

WATERY SUBSTANCE AND STARCHES ARE A GOOD CONDUCTOR OF ELECTRICITY.

BYE!!!

CHEERS!!!!!!!

 A potato will work as a conductor in an electrical circuit if the voltage is high enough. You, however, want one to work as a battery. The potato has electrolytes in it that will encourage electron flow if a copper strip (or a penny) and a zinc strip (or a galvanized nail) are inserted into the potato to complete a circuit. A single potato will probably not provide enough current to light a light bulb, but may light a low current LED.

Their is acid in every fruit and vegetables. As we know acid, base and salt make substance a good conducto. So the acid present in it makes it a good conductor.

because its contains acid
