Vegetable oil is not a good conductor of electricity.
* Substances which have a higher electron mobility or free electrons are good conductors of electricity.
* Tap water can conduct electricity due to the presence of salts or minerals that can form free ions.
Distilled water is not a conductor of electricity.
* Vinegar is acetic acid which can dissociate to form ions and thereby conduct electricity.
* Lemon juice contains citric acid and thereby can form free ions in water. This makes it a conductor of electricity.
* On the other hand, vegetable oil do not form any ions and hence cannot conduct electricity.
