Current through capacitor superposition

[jongunwon]

In Posted Image Circuit, I want to calculate the current through the Capacitor C1.

Maybe Currents through C1 are composed of 2 path : Decay process due to Voltage difference between 2.3V, 1.5V and Independent Ideal current source

Because the current source is ideal independent current source, Can we solve the problem using superposition method?

for example, 1) Open the current source + 2) Only operate current source without the decay process

Hi,

I see no information about AC, thus I assume it is DC only.

--> there is no DC current flow through a capacitor. Zero.

Btw: on an ideal capacitor no (zero) electrons go "through" a capacitor ...in the meaning of "passing the dielectric".
But the same ammount of electrons that go "into one pin" of the capacitor will go out at the other pin of the capacitor.
Thus it looks like the electrons go through the capacitor.

The current source changes its own voltage to whatever amount pulls its spec current through the circuit. Initially it may be low amplitude. However I think eventually it goes to infinite voltage since there only seems to be continual charging of capacitors C1 C3, and no discharge cycle.
