Light Bulb Question

Just had electronics and photonics sac, in one of the question you had 4 light bulbs with two of the bulbs being parallel to other two in a circuit with 12v. The question told you the bulbs had a power rating of 1.5W, 3V. When one of the switches was closed all these volts ended up in one of the bulbs. The question asked you to describe what happened to the bulbs when this switch was closed, is it right to assume that the 12v would overload the globe and cause it to burn out?
