A student is testing a circuit to determine if it is in series of parallel. Which of the following tests correctly identifies the type of circuit? * 20 points
If the bubls are equal brightness, it is a series circuit because each bulb will have to share the same current.
If all the bulbs are equal brightness, it is a parallel circuit because each bulb in a parallel circuit has its own path to the battery.
If one bulb is unscrewed and the others stay lit, it is a series circuit because each bulb in a series circuit has its own path to the battery.
If one bulb is unscrewed and the others stay lit, it is a parallel circuit because each bulb in a series circuit has its own path to the battery.
