The net capacitance in the circuit above is
-
A.
80µF -
B.
6.0µF -
C.
4.0µF -
D.
2.0µF
Correct Answer: Option D
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
(frac{1}{C}) = (frac{1}{4}) + (frac{1}{4}) = 1 + (frac{1}{4}) = (frac{2}{4})
C = (frac{4}{2})
= 2µF
