Question: If you remove a single bulb from an inexpensive string of Christmas tree lights, all of the lights in the entire string will go off. Are the bulbs connected in series or parallel? Explain.

Answer: All of the bulbs in this string of Christmas lights are connected in a series circuit. In a series circuit, all bulbs are powered through one “route,” so if any bulb is removed, the circuit’s connection from Start to Finish will be interrupted and shut off all lights.
