Answer:
4 volts
Explanation:
The diagram to the question is attached below.
Given that:
the battery voltage is = 12 volts
and the lights bulbs are identical; we can see that there are 3 light bulbs shown in the diagram below:
We can also see that the circuits are connected in series: if one light bulb happens to be removed from the circuit, the remaining light bulb will go out.
Thus; the voltage on each bulb since they are identical = V/3
= 12/3
= 4 volts
