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 lightbulbs, 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.
1. increases
2. decreases
3.remains unchanged

b. Individual currents in the bulb.
1. increases
2. decreases
3.remains unchanged

c. Power delivered by the battery.
1. increases
2. decreases
3.remains unchanged

d. Lifetime of the battery.
1. increases
2. decreases
3.remains unchanged
