When Two or more than Two capacitors are in series then
Total capacitance is :-
T.c = 1/c1+1/c2+1/c3....
= 1/0.47+1/0.33+1/0.1
= 0.066
Total capacitance is :-
T.c = 1/c1+1/c2+1/c3....
= 1/0.47+1/0.33+1/0.1
= 0.066

The formula is reverse to the resistor so,
1/c = (1/c1+1/c2+1/c3).
= (1/0.47)+(1/0.33)+(1/0.1).
= 15.15.
c = 1/15.15.
c = 0.06microfarad.
1/c = (1/c1+1/c2+1/c3).
= (1/0.47)+(1/0.33)+(1/0.1).
= 15.15.
c = 1/15.15.
c = 0.06microfarad.

1/(1/C1+1/C2+1/C3)=0.06600

If circuit shows the capacitors connetced in series so
formula is ct = (c1*c2)+(c2*c3)+(c3*c1)/c1*c2*c3
= (0.47*0.33)+(0.33*0.1)+(0.1*0.47)/0.47*0.33*0.1
= 0.1551+0.33+0.47/0.1551
= 0.2351/0.1551
= 0.659micro farad
formula is ct = (c1*c2)+(c2*c3)+(c3*c1)/c1*c2*c3
= (0.47*0.33)+(0.33*0.1)+(0.1*0.47)/0.47*0.33*0.1
= 0.1551+0.33+0.47/0.1551
= 0.2351/0.1551
= 0.659micro farad

This Capacitor are in series.
So, C1 + C2 + C3 = 0.9.
So, C1 + C2 + C3 = 0.9.

C1+C2+C3 = 0.47+0.33+0.1 = 0.9

1/c1+1/c2+1/c3=.066

@ravi ur answer is rite for parallel connection.

@Dwa your explanation is correct.

Here capacitor is in series so c1+c2+c3..
So ans is 0.9.....1/c1+1/c2+1/c3 is parallel formula.
So ans is 0.9.....1/c1+1/c2+1/c3 is parallel formula.
