I'm interested specific on electricity consumption changes on 2 different situations inside an elevator.
- When the elevator is stopped and people enters the elevator, does it change in any way the electricity consumption? Simple logic tells as that the elevator in this state is stopped by brakes, and brakes pressure is not affected by the amount of people being inside the elevator, so there should be no difference on electricity consumption on this case.
- If elevator is going up/down, and a passenger is walking, jumping inside the elevator does this makes any difference on power consumption of the elevator? or regarding the external motor we can see all the cabinet as a unit and the forces that interact inside the cabinet doesn't change anything regarding the external force that is trying to make all the cabinet move ? If it's true how is called this principle?
