Homework Help: Capacitance, Potential difference

  1. Jun 4, 2015 #1
    1. The problem statement, all variables and given/known data
    Find the potential difference Va-Vb between points a and b.


    2. Relevant equations

    3. The attempt at a solution

    Each capacitors left plate will have difference amount of positive charge and right plate will have negative charge. After that i don't know how to proceed.

    If the capacitors are uncharged prior to being placed in the circuit, then the net charge in the part of the circuit right of the capacitors is zero initially.

    I don't see how all of the right plates for all of the capacitors can be negative.

    If you are familiar with KVL, you can use it for the 3 loops to get the voltage across each capacitor.. Just find the potential of point b, assuming a as ground(0V).

    Use KVL
