Homework Statement


The attached file has a circuit reduction which I can understand all but the missing capacitance C between B' and C' to the ground each from figure (a) in figure (b)


Homework Equations


N/A

The Attempt at a Solution


Shouldn't there be another capacitance of 2C in the bottom line of figure (b)?

Looks like the voltage sources have been suppressed (Thevenin?). Thus B' and C' both are grounded through the shorted supplies. Both ends of those two caps are thus grounded... and they disappear in a puff of logic :smile:
