Ok, (an embarassing question) well I know an electric fan is relatively low wattage compared to say an electric kettle (while both on for the same amount of time). But also that smaller resistance draws more current than larger resistance, and by this logic (v2/R or I*R) the smaller resistance uses more power. To reitterate the electric fan uses less power than the kettle (or water heater, air con etc.) so what is this model failing to take into consideration? Power factor or something? Thanks!
