Consider the following circuit
Capacitor C2 is charged up to 1V from an external source before-hand. The top plate of C2 is connected to the bottom plate of C1. The top plate of C1 is at a voltage of 0.25V
Due to the increase in voltage across C1, the charge on it must increase according to Q = CV. This is fine for the top plate of C1 which can get it's +Q charge from the 0.35V source, the bottom plate however must receive the increased (-Q) charge from the C2 capacitor.
Thus, negative charge flows from top plate of C2 to bottom plate of C1, hence conventional current flows to C2, charging it up further and increasing it's voltage to 1.1V (random chosen value to illustrate).
Is this correct? It seems wrong to me. I know I can calculate this with maths, but I really want to understand intuitively how charge is moving. I can't find any resources online that talk about charge moving in detail. I don't care about exact values, I just want to understand roughly what's happening.
