Charistmas lights 2 by rent2u on 04-27-2008
Hey you are right! I replaced one bulb and they all lit up.
Let's try another string!
Ok, this one only has one bulb not working. What's with that?
That string must be a parallel circuit.
What is a parallel circuit?
It's a circuit where each light does not depend on the other lights to burn.
