Say for example a company provides a vaccum cleaner in a 1400w basic and a high powered 1800w? what makes a motor draw more power?
Power = V*I, so assuming the voltage is the same, the current must have increased. To increase current, you need to reduce resistance. So what exactly changes in the higher powered motor?
Is artificial resistance added to the lower powered motors so that they dont have to be built as well, cutting down costs, hence it being cheaper?
And less artificial resistance added to the higher powered motors, meaning they need to be built better, as such increasing costs, hence it being more expensive?
