Suppose you have three identical lightbulbs, some wire, and a battery. You connect one lightbulb to the battery and take note of its brightness. You add a second lightbulb, connecting it in parallel with the previous light bulbs, again take note of the brightness. Repeat the process with the third lightbulb, connecting it in parallel with the other two. As the lightbulbs are added, how are the following properties affected?
a. Brightness of the bulb
i. Increases
ii. decreases
iii. remains
iv. unchanged
b. Individual currents in the bulb
i. Increases
ii. decreases
iii. remains
iv. unchanged
c. Power delivered by the battery
i. Increases
ii. decreases
iii. remains
iv. unchanged
d. Lifetime of the battery
i. Increases
ii. decreases
iii. remains
iv. unchanged
