in the circuit shown in the figure each capacitors is of 3F the equivalent capacity between the AandB is
hi,
you did not give the circuit details, whether the capacitors are in parallele or in series. suppose the two capacitor c1, c2 are in series than equivalent will be
equivalent for two series capacitor=(c1*c2)/(c1+c2)
if the capacitor are in parallel then equivalent is =c1+c2.
capacitor rules is opposite to resistor and inductor.
