There is something I don't understand. If we have a 9 V battery cell and the cell is connected in a circuit with 3 bulbs, the voltage would be divided between the 3 bulbs so each bulb gets 3 v. If we have 2 bulbs, the voltage becomes 4.5v each. Why do circuits behave as it it is all preset? How do electrons "know" before it reaches the first bulb that it has another bulb alond the way and that you can only "devote" 4.5 v of electrical energy to the first bulb?
