Ceq of 3 capacitors in a triangle

  1. Oct 15, 2011 #1
    I'm a little confused about this problem. I attached the pic. The solution manual states " capacitors C1 and C3 are in
    series with each other and in parallel with capacitor C2."

    I don't understand why it has to be C1 and C3 in series which is parallel with C2.

    Can't it also be C2&C3 in series and parallel with C1

    Which two of the vertices, a, b, c, are assumed to be the terminals?

    Please state the whole problem as it was given to you.

    Oh they said "find an expression for the equivalent capacitance between points a and c in terms of the 3 capacitance values." But they didn't say they were the terminals tho, unless that statement implies it.

    Yes, the statement implies it.
