Hi I have a question regarding the charge Q that would build up on capacitors in series when there is a potential difference between the plates.(adsbygoogle = window.adsbygoogle || []).push({});

Consider the attached circuit.

1. Knowing the potentials [tex]\phi_A, \phi_B[/tex] and the capacitances [tex]C_A, C_B[/tex], butnot[tex]\phi_C[/tex] is there a way of calculating the charges on the plates?

2. Is [tex]Q_A=Q_{Ca}[/tex] and [tex]Q_B=Q_{Cb}[/tex]?

3. Is [tex]Q_{Ca}=Q_{Cb}[/tex]? If not, what would prevent charge flowing from one plate to the other?

4. The series capacitors are equivalent to a single capacitor having capacitance

[tex]C_T=(C_AC_B)/(C_A+C_B)[/tex] and hence charge [tex]Q_T=C_TV[/tex]. Is [tex]Q_A=Q_B=Q_T[/tex]?

Sorry this is so long winded, and thanks in advance.
