A circuit contains a 12 volt battery and two 3- ohm bulbs in a series. What is the voltage across each branch?

If the bulbs are in series, then there are no 'branches' ... just
a single current path all the way around.

If the two bulbs have equal resistance, then no matter what their
actual resistance is, the supply voltage will divide equally between
them ... 6 volts across each bulb.
