Textbook Question
Chapter 20.2, Problem 1aTH

1. The circuit at right consists of a bulb in series with an electrical “black box.”

The following are possible contents for the “black box.” All the bulbs are identical. Box C consists of a single piece of connecting wire.

Suppose that each of the five boxes is placed, in turn, into the circuit. (Only one box is in the circuit at a time.)

a. Draw the appropriate five circuit diagrams below (show the contents of the boxes in place of the box itself).
