What would happen if 2 capactors, in series which each another with 1 higher voltage and 1 at lower voltage do while connected the the amplifier as well? for eg.


-----||--------------||---------(amplifier)
C1 C2

If c1 has a voltage of 2volts and C2 has a voltage of 5V....

would C2 share charge with c1? thx
 
Up to a point. It depends on the source impedance, load impedance, and capacitor values.

Here's a simplification to start with: Imagine Zsource=Zload=0 Ω and that C1=C2. The junction of C1 and C2 must be at the same voltage, so C2 has to dump a load of charge into C1 to equalise the potentials.

Are you saying that no matter what voltage is across the two capacitors in series that the voltage and current will balance. Does not the capacitance decreases when placed in series?
