Infinity Learn · Accepted Answer

The given circuit is equivalent to Wheat stone's bridge. when the bridge is balanced, the upper two condensers between A and B will be in series. Their resultant capacitance would $$be1C$$′$$=110+110=210=15or$$     C′$$=5$$μFSimilarly, the lower two condensers between A and B are also in series. Their resultant capacitance would be $$1C$$′′$$=110+110=210=15or$$    C′′$$=5$$μFThe capacitor C' and C'' will then be in parallel. Hence the effective capacitance between A and B will be $$C=C$$′$$+C$$′′$$=5+5=10$$μF
