IV: Removing/Breaking a bulb
DV: Its affect on the non-broken bulbs.
If the Christmas lights are arranged in a parallel circuit, then when 1 bulb bursts the other bulbs will light up.
If the Christmas lights are arranged in a series circuit then when 1 bulb bursts the other bulbs will not light up
A parallel circuit is the best series to use for Christmas lights because it is faster. Along with this, it’s more efficient, as evidenced by the Phet Simulator. And, unlike the series circuit, the parallel circuit allows the other lights to keep working if an individual bulb were to break. So, it only makes sense that you use a parallel circuit. Plus, in the parallel circuit, the flow of energy through the wires was much faster and the blubs were much brighter.
