I have this exam coming and looking through some old questions I can't figure this one out:

It's the second question and it goes at follows:
a) Switch S1 is closed. How big of a current goes through S1 immediately after closing it?
b) How big of a current goes through S1 after a long time closing it?
c) How big is C2 charge after a long time since slosing S1?
d) Switch S2 is closed. How big of a current goes through S2 after a long time closing it?
e) How big is C1 charge after a long time since slosing S2?
f) Switch S1 is opened. How large is C1's charge after a long time?

ty in advance.

Instead of asking for homework help perhaps you should go study the rules for dealing with RC circuits? Giving you the answers to these questions won't help you understand why they are the answers, so when you encounter a similar problem on an exam you're going to get it wrong. And if you have studies those rules and are still stuck on something you should post exactly what you're having trouble with instead of asking for an answer to the whole problem.
