... To go from the top to the bottom floor, all people must take the same path. So, by definition, the staircases are in series. With each flight people lose some of the potential energy given to them by the elevator, expending all of it by the time they reach the ground floor. So the sum of the V drops ...

... You are more likely to find a 1K ohm resistor than a 1.2K ohm resistor so use a 1K ohm resistor in 12 volt systems N scale type layouts. Generally you’ll find that a 1K ohm resistor value will work fine in higher voltage HO scale layouts as well - the current flowing through the LED will be higher b ...
