How does a light circuit affect the strand of Christmas lights with a burned out bulb ?
The light circuit
The light strand
I noticed that no matter what you did the bulbs would stay lit until you removed the battery.
This is evidence of the parallel circuit working when you disconnect a bulb.
When one bulb goes out they all do. If the series circuit has a bulb that breaks then all bulbs on the circuit will go out.
a series circuit while it has all it bulbs
A series circuit with one bulb missing.
In conclusion the parallel circuit is the better circuit. When one bulb bursts or goes out the other will stay lit. With a series circuit when one goes out all will go out. Another reason is parallel circuits catch fire much less than a series circuit.
