                                                   1.   In the following circuit, which bulb lights first?

                                                        A)   Bulb A
                                                        B)   Bulb B
                                                        C)   Bulb C
                                                        D)   They all light at the same time
                                                        E)   A and C light first, B lights after them.




Study the three loops shown below. For each loop, state which of the bulbs will light when the connections are
made.

                 A)   bulb A
                 B)   bulb B
                                                                           3. ___________

                 D)   neither bulb                                               A)   bulb A
                                                                                 B)   bulb B
                                                                                 C)   both bulbs
                                                                                 D)   neither bulb




                                                                             5. Using a colored pencil,
                                                                             go back and trace the
                                                                             continuous conducting paths
                                             4. ___________                  in numbers 1 – 4.

                                                   A)   bulb A

                                                   D)   neither bulb
   5. Draw the continuous Conducting path through this bulb and socket.




           Start in this                                                              End in this
           connecting wire                                                          connecting wire




   6. Examine the picture below. You have a battery pack and three cells arranged like so. You are given two
      wires to make all three bulbs light.

a) draw the wires
b) in another color, trace the Continuous Conducting Path (CCP) through the circuit – this includes through the
   filaments of the bulbs and the batteries!




   7. Homer and Hilda found a way to light two bulbs with a 3-cell battery and only 2 wires! Trace the CCP
      throughout the entire circuit.

Here are some more attempts from Homer and Hilda. Your job is to trace the CCP and determine which of the
bulbs will light. Note: the bulbs are always touching each other.
