Answer:
Similarities :
Series: In these series wiring, the positive current flow on the left and negative current flow on the right.
Parallel: in these parallel wiring, the current flow is the same like the series wiring.
Differences:
Series: the wiring of series is simply easy, it flows from one direction. If the wire is cut or lose, the possibility of two bulbs will lose too.
Parallel: The wiring of parallel is simply complicated, it flows 2 or more directions. It the wire is cut or lose the other bulbs will be on power but the other lose wire in the other bulbs will lose.
It's better to be in parallel wiring. but in series wiring if the wire is cut you will know that all bulbs are off.
