As the current is generated by the electron flow generated by the phosphoric acid in the potato reacting with the zinc and copper electrodes, I would assume that the apple has a lower pH, generating a more vigorous reaction and causing a higher current. Assuming the resistance is constant, and using Ohms law, the higher current would result in a higher voltage.

Since you can make many potato chips out of one potato, obviously a whole potato has more mass than one potato chip.

It doesn't, a lemon has more voltage than an apple because a lemon has a higher amount of acidity. The more acidity a fruit has, the more voltage it has. [NEEDS CORRECTION] (Acidity in foods does NOT correlate to the amount of voltage produced. See University of Illinois, Physics Department {Q & A: Fruit Batteries | Department of Physics | University of Illinois}.)
There are 5 major differences between a potato and a sweet potato, only a couple of which are easy to detect. Color - A sweet potato will be darker inside than a potato. Sweetness - A sweet potato has about 4 times the sugar of a potato, enough to detect by taste. Sodium - Although undetectable by taste, a sweet potato has about 10 times the sodium Vitamin A - A sweet potato has more than 1000 times the Vitamin A than a potato Beta-Carotene - A sweet potato has more than 1000 times the beta-carotene than a potato.
No
yes more voltage
Potato more than onion, but both have some.
number of turns......... If turns is more than more impedance..
It breaks down the potato faster because the liver contains more of an enzyme called catalase in it than the potato.
the liver has more enzymes that the potato (a starch) does.
potatoes contain more catalase than carrots
An orange has more protein than an apple.
