A shopping mall is putting up lights for the holidays. When they plug the holiday lights in they do not light up.

What kind of circuit are the Christmas lights on?

What can the employees do to make the lights work?

Anybody who has dealt with Christmas Tree lights knows what can be done. You must take a bulb you know to be good and try each bulb in turn until the whole string lights up. If two bulbs are dead, give up and go buy another string. Two bulbs create a lot of combinations.

The circuit is a series circuit.
