In general, the size of the burner on a cooking range does not directly affect its electricity consumption. The primary factor that determines electricity usage is the power rating or wattage of the burner.
Electric burners have different power ratings, typically ranging from 500 watts to 2500 watts or more. The power rating indicates the amount of electricity the burner consumes per unit of time when it is in operation. Burners with higher power ratings will consume more electricity than those with lower power ratings, regardless of their physical size.
When using a smaller burner, you may use less electricity if you're using it at a lower power setting compared to a larger burner at a higher power setting. For example, if you use a smaller burner set to 1000 watts and a larger burner set to 2000 watts, the larger burner will consume more electricity.
It's important to note that while smaller burners may have lower power ratings, they also have limitations in terms of the amount of heat they can generate. Therefore, cooking times may be longer on smaller burners compared to larger ones.
