Homework Statement


I am given a circuit wherein there is a capacitor C1 followed by a battery of PD E1 followed by a capacitor C2 followed by a battery of PD E2 connected back to C1. Find PD across C1 (v1) and C2 (v2)

| _ E2_|

C1 = = C2
|_E1_|

Homework Equations


Kirchoffs loop equation


The Attempt at a Solution


Applying Kirchoff's law we have,
E1 - V2 - E2 + V1 = 0
E1 - E2 = V2 - V1
Now what??

You know that charge cannot flow between the capacitors, so the charges on them are equal.

Charges cannot flow alright. But how do you know they are equal?

I was extremely sleepy when doing this stuff. Obvious answers now that I've woken up. I wasn't even thinking. I don't even remember coming on here and making this thread. VERY SLEEPY. My mistake.
