Dear members,
I am modelling a fluidic systems by means of simulating it as an
equivalent electrical circuit. I have a few doubts and please help me
in solving it

I am modelling a fluidic capacitance which consists of a membrane
deflected by means of pressure diffrence. hence there is no fluid flow
across the membrane.here I have some doubts.

1. In electrical capacitance , is there is a flow of charge through
the capacitor.
   because physically the capacitance has a dielectric or an insulator
which cannot pass charges in it.

2. so when I am measuring current across the capacitor what exactly I
am measuring ? . Is it the charge difference between the two plates.

3. where can I learn more about capacitance. because as an electrical
engineer I always think about alternating current flowing through the
capacitor

Thank you
