Question

why vegetables cannot be used electrical conductors​

Answer 1

The best food battery is any fruit or vegetable that has high levels of superconductive ions, such as potassium or sodium, and the proper internal structure to create a working current. Potatoes, which have homogenous structures, and pickles, which have high levels of sodium and acidity, are good examples of such foods.
