1. The problem statement, all variables and given/known data I have a 12 volt battery and 3 lamps in series. -O---O---O- The last one is broken. What is the voltage on every lamp? 2. Relevant equations 3. The attempt at a solution My book is saying that the current through the lamps that are not broken is 0 cuz the circuit is not "complete" therefore the voltage on the lamps that are not broken is 0. (I understand this). But then the book is saying that the voltage across the broken lamp has to be 12 volts. So I wanted to see what would happen if the first lamp is whole but the two last lamps are broken. Would that mean that there is 6 volts on every broken lamp?
