Which fruit or vegetable has the most electric charge in it?

The potato has the most electric charge in it.

Use a multimeter to measure the electric charge. Some fruits or vegetables are close to be the most electric charge, but it's not at least high enough compared to the potato I used.
Out of all fruits (lemon, Apple, banana, etc...), the potato has the most electric charge in it. All the other fruits or vegetables are close, but the potato wins it all! :P

You could use a multimeter to measure the electric charge. Test all the fruits and vegetables to find out what the charge is. :)
