Question

Question 8 10.5 pts A capacitor of 16 micro-farads is connected to a 18 volt battery. The distance between the plates of the capacitor is reduced by a factor of 4.7 while the capacitor is still connected to the battery. What is the voltage across the capacitor after the distance between the plates is changed, in volts? Question 9 10.5 pts A capacitor of 20 micro-farads is connected to a 18 volt battery. The distance between the plates of the capacitor is reduced by a factor of 4.2 while the capacitor is still connected to the battery. What is the capacitance of the capacitor after the distance between the plates is changed, in micro-farads? Question 10 10.5 pts A capacitor of 9 micro-farads is connected to a 15 volt battery. The distance between the plates of the capacitor is increased by a factor of 2.5 while the capacitor is still connected to the battery. The battery is then disconnected from the plates, and then the plates are moved closer by a factor of 5.3. In their final configuration, what is the charge on each sheet in micro-coulombs?

Explanation / Answer

8)

Since the capacitor is still connected to the battery, the voltage will not change, it will remain the same as before.

Thus,

V = 18V
