Each light switch in the classroom allows you to turn on one row of lights. What conclusion can you make about how the rows of lights are connected and justify this answer. A) The rows must be hooked up in parallel or only one row could be turned on at a time. B) The rows must be hooked up in series or all the rows of lights would either turn on or off. C) The rows must be hooked up in parallel or all the rows of lights would either turn on or off. D) The rows must be hooked up in parallel or all the rows of lights could only be controlled by a single switch.

The answer is B.) The rows must be hooked up in series or all the rows of lights would either turn on or off.

In circuit analysis having a series connection the supply of current is shared amongst all the loads on the line. Given in this problem we have a load as the lights which are in series. Connected in a way such that when one switch goes off the rest of the light goes off since the connection starts from the positive end of the source into each light from positive to negative ends and back to the negative end of the source.
