Question

The effective capacitance in uF in between A and B will be
1) 28/9
2) 4
3) 5
4) 18
​

Answer 1

Answer:

4

Explanation:

4 is the right answer of this question

Answer 2

Answer:

5μF

Explanation:

Cp=C1+C2

C'=2+2=4μF

C' and 12μF are connected in series

1/Cs= 1/C'+1/C3

1/C"= 1/4+1/12

1/C"= 3+1/12

1/C"= 4/12

C"= 3μF

As C" and 2μF are connected in parallel

Cr= C"+2

Cr= 3+2= 5μF
