Current vs potential difference light bulb
Weba) both bulbs go out b) the intensity of both bulbs increases c) the intensity of both bulbs decreases d) nothing changes Before switch closed: V a = 12V because of battery. V b =12 because equal resistance divides 24V in half. After switch closed: Nothing changes since (a) and (b) are still at same potential.
