Homework Help: Electrical Circuit Exercise, please help.

  1. May 12, 2007 #1
    Hi, I need help with the following exercise:

    1. The problem statement, all variables and given/known data

    We have a square circuit, with 4 capacitors, 1 on each side of the square, all with the same capacitance C. Calculate the total capacitance of the system of capacitors between the two diagonally opposite corners of the square, A and B.

    This is how I solved it, could you tell me if it's right?

    A ) 2 capacitors (from A to B ): they are in series
    B ) 2 capacitors (from B to A): they are in series

    A )1/Ceq = 1/C1 + 1/C2= 2/C --> A-Ceq=C/2
    B )1/Ceq = 1/C3 + 1/C4= 2/C --> B-Ceq=C/2

    Now A-Ceq and B-Ceq are in a parallel configuration:

    C) Ceq = C/2 + C/2 = C

    The total capacitance is equal to C?

    Thank you.
