Ok, so if you have a 9v battery and connect 2 bulbs to it (in series) each bulb recieves/uses 4.5v right?
And if you have 3 bulbs then 3v per bulb etc.
But how does the bulb "know" to only use 3v? You would think the first bulb would use 9v and then there's none left for the other 2.
Can anyone explain this?
Thanks.
