2:10 1 l 5GEO Done Circuits (3 of 5) Part 2: Lightbulbs 1) Consider the circuit above, where A, B, and C are equal lightbulbs. What do you think it will happen to the brightness of A and B when you close the switch? For each, say if it will increase, decrease or stay the same. Make a guess based on your intuition and write it here. 2) Now with your circuit board build the three-blub circuit as in the figure above. Keeping the switch OPEN, what can you tell about the brightness of A and B? 3) Now close the switch, what happens to the brightness of A and B and C? 4) Does what you see in your circuit match your prediction in part 1)? 5) Using circuit analysis find an expression for the current through A and B when the switch is OPEN. !!!
