## Capacitors in series and parallel

A battery of potential V stores charge q on a combintation of two identical capacitors. What are the potential difference across and the charge on either capacitor if the capacitors are (a) in parallel (b) iin series?

I know the answers to these questions but I'm trying to understand the conceptul ideas behind this question. The answers are:

(a) V, q/2

(b) V/2, q

Any ideas?

 Do you understand the concepts behind parallel vs. series capacitors?

Yes I do, but could you elaborate a little?

anyone else have any inuput?
 Recognitions: Homework Help Voltage is potential difference . (V_C - V_B) + (V_B - V_A) = (V_C - V_A). Charge is conserved, just like mass is.

What does the 'B' stand for ?
 Recognitions: Homework Help A, B, C are locations. Potential (V) is a function of location. Voltage, a potential DIFFERENCE, is a function of a REGION (Capacitor gap). with Capacitors in series, A is bottom plate, C is top plate, B is either middle plate.
