Take C1 = 4.0 μF and C2 = 6.0 μF in figure. Calculate the equivalent capacitance of the combination between the points indicated.


Let's name the points indicated in fig as A and B.


In a) C1 and C2 are in parallel. If we redraw the diagram that will look like









In b) also C1 and C2 are in parallel. Redraw the diagram.








Ceq=Ca+Cb=5+5=10μF



Equalent capacitance in figa) is 5μF.


Equalent capacitance in figb) is 10μF.
