opps on my last reply. I didnt see that tk posted the series battery circuit. 

A and C are equal brightness. B is not lit. 24v on meter.

Bulb B should have 0v across it. As if it were not in the circuit. A and B will have 12v across each.

Meter reads 0v.  ;]  I made the same mistake(tricky for some odd reason) that the batteries were in series. They are not.  maybe it is the meter presence that confuses what we think we see of the batteries and their polarity to each other.

Look back, there are 2 separate koans, one with the batteries antiseries and the other in series. Both are puzzlers.

@PC: the A and C bulbs are in series, are they not?

Slow down. Two separate circuits, both to be considered. Koan 1: batteries in antiseries. Koan 2: batteries in series. Same questions, same bulbs, same same.

But B is in series with one 12 v battery and bulb C (removing the top of the circuit), and it's also in series with the other battery and bulb A (removing the bottom). Why should it not be lit at normal 12 volt brightness?
