Ans given in this qus is (d) but i am getting (c) . Explain

Q.  If three capacitors each of capacity l μ F are connected in such a way that the resultant capacity is 1.5 μ F, then                      [MP PET 1989]

A) All the three are connected in series
B) All the three are connected in parallel
C) Two of them are in parallel and connected in series to the third
D) Two of them are in series and then connected in parallel to the third
 

Dear student,

Connecting the two in series C'=1×12=0.5μF   Now connecting this in parallel with third oneC=0.5 +1 =1.5μF             

so option d is correct

Regards
