Based on the results in Experiment 2, which one of the following rules accurately describes the effect of the number of bulbs upon overall current and overall resistance?
a. Increasing the number of bulbs will cause both the current and the resistance to increase. b. Increasing the number of bulbs will cause both the current and the resistance to decrease. c. Increasing the number of bulbs will cause the current to increase and the resistance to
decrease.
d. Increasing the number of bulbs will cause the current to decrease and the resistance to
increase.
