There are three capacitors. One is in parallel with two others. The two others are in series. The alone one is 2.8 uF, the other two in series are 4.4 and 3.7 uF. a 12 volt voltage is applied. Initially there is a bridge that connects to the 2.8. After it is charged, the switch is thrown. What are the final charges on each?
This one throws me because I'm not sure what happens after the switch is thrown. Does the voltage cease to be applied? or is it still applied? if it is still applied, then I'm not sure how the built-up charge in the 2.8uF capacitor matters.
