The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.
Depends. Whats the amperage rating on the bulb and the battery? Is  the 12 volt bulb LED? The equation to find your answer depends on  how much your 12 volt bulb is drawing and how much your battery  has. I have seen 12 volt bulbs that are searchlights and I have  seen 12v bulbs that are little...
