this may sound strange because most people say it will be lemon or something acidic but actually i did that experiment and it is kiwis.
Any fruit or vegetable that has a high concentration of ions will conduct electricity well. Anything soaked in a brine (pickled) or sour tend to have high ion concentrations. Lemons and pickles are the best two that I have ever seen.
Potato is known to be able to conduct electricity relatively well due to its high water and electrolyte content. When a potato is used in a battery experiment, the electrolytes in the potato help facilitate the flow of electrical current. Other fruits and vegetables with high water content, such as lemons and tomatoes, can also conduct electricity to some extent.
I would say that salt water would conduct electricity best.
All fruit has some moisture and, for that reason, all will conduct electricity to some extent. Fruits that conduct electricity best will be those that are juicy with lots of dissolved acid or salts. On a 1 to 10 scale where 10 is best: roasted nuts and banana chips are 1; citrus and tomatoes a 10. Do a web search for "electrolyte".

humans conduct electricity because your body is made 70% of water. so its the best conductor.
any citrus fruit (such as lemons and limes) is a good conductor of electricity
Yes, Pencil Lead does conduct Electricity. Copper, Gold and Silver though are the best conductors.
Metals conduct electricity the best, as they have many free electrons that can easily move and carry electric charge. Plastic and wood, being insulators, do not conduct electricity well due to their lack of free electrons.
nonmetals
Electricity does not conduct heat. Your question is meaningless.
