Find the capacitance of the combination shown in the fig; in between. A and B.2uF2uF2μ2pF2uF1PF1 pF1 PF

Answer»

We know that for capacitors in series,C=C1*C2/(C1+C2)and for capacitors in parallel,C=C1+C2

Starting from the left side, and taking 2 capacitors at a time,

2uF and 2uF are in series, equivalent is 1uF.This 1uF is in parallel with 1uF, equivalent is 2uF.Proceeding in the same manner, we getequivalent capacitance between A and B= 1uF.
