6. Connect circuit (b) in Figure 2-2. Begin graphing current as above, and record the measured values of the currents. Current through bulb B: Current through bulb C: Question 1-5: Consider your observation of the circuit with bulbs B and C in it. Is current "used up" in the rst bulb or is it the same in both bulbs? Explain base d on your observations. Question 1-6: Is the ranking of the currents in bulbs A, B, and C what you predicted? If not, can you explain what assumptions you were making that now seem false? Question 1-7: Based on your observations, how is the brightness of a bulb related to the current through it? Question 1-8: How does the amount of current produced by the battery in the single bulb circuit (Figure 2-13] compare to that produced by the battery with two bulbs connected as in Figure 2-lb? Does the addition of this second bulb in this manner affect the current through the original bulb? Explain. Question 1-9: Suppose you think of the bulb as providing a resistance to the current in a circuit, rather than something that uses up current. How do you expect the total resistance in a circuit is affected by the addition of more bulbs in the manner shown in Figure 2-1b
