Circuit problem+

Can someone PLEASE help me set this up!! I will be so grateful!!

The ammeters and the voltmeters in the circuit of the figure are to be assumed ideal. Find:
a) the readings of the meters immediately after the switch is turned on;
b) the readings of the meters a long time after the switch was turned on;
c) the final charges on each capacitor.



Greatly appreciate any help at all!!

AC or DC?

Since no-one else has posted a reply, I will give it a go (at least parts 1 and 2)

Capacitors allow a changing current to pass, but not a constant current.
The charging of one plate of the capacitor causes a charge to build on the other plate until such time as an equilebrium is reached.

So when the current is initially applied, the capacitors will act as conductors.
After a while the charges on the capacitors will reach equilibrium, then they will act as insulators.

Thus
for a) replace the capacitors by wires in the circuit,
for b) treat the capacitors as breaks in the circuit.
