If a fan is switched on at regulator speed 1, does it use as much energy 
as when it is turned on at regulator speed 5? What actually causes a fan 
(or for that matter, other electrical appliances with regulators)to move 
faster - is it the amount of current flowing through? An air-conditioner 
has a stated power wattage, but it can be set at different controls. Does 
it still use the same energy and power for the different controls?
