The net capacitance in the circuit below is?

 

A. 80µF
B. 6.0µF
C. 4.0µF
D. 2.0µF

Correct Answer:

Option D – 2.0µF

Explanation

For capacitance i n parallel, 2µF and 2µF are in parallel, their equivalence is 2µF and 2µF = 4µF

The 4µF generated is now in series with the remaining 4µF.

The net capacitance for series connection is

1/C = ¼+ ¼= 1 + ¼= 2/4

C = 4/2

= 2µF
