Final answer:
Cooking oil is not a good conductor of electricity due to its low density of free electrons.
Step-by-step explanation:
Cooking oil is not a good conductor of electricity.
In order for a substance to conduct electricity effectively, it needs to have a high number of free electrons that can carry electrical current. While cooking oil may contain some impurities that can make it slightly conductive, it is not a reliable or efficient conductor of electricity.
Good electrical conductors, such as metals like silver, copper, gold, and aluminum, have a high density of free electrons. These materials are commonly used for electrical wiring and cooking utensils.
