Testing a parallel circuit
What do you think would happen to the brightness and the voltage of each bulb if you added a third bulb to your parallel circuit. Make a drawing of the circuit. Next to each bulb on the drawing write your prediction for the voltage across the bulb.
Using the same steps as in "Investigation I" test each bulb in the circuit. In a different color write the actual voltage reading next to each bulb on your drawing. Refer to Technical Hints to see how to use the CC DMM program.
Go to Questions 5, 6, and 7 in the "Analysis".
