A) \[1\mu F\]
B) \[2\mu F\]
C) \[4.5\mu F\]
D) \[6\mu F\]
Correct Answer: D
Solution :
[d] Possible combination of capacitors |
(i) Three capacitors in series combination |
\[\frac{1}{{{C}_{eq}}}=\frac{1}{3}+\frac{1}{3}+\frac{1}{3}\]\[\therefore \]\[\frac{1}{{{C}_{eq}}}=1\mu F\] |
(ii) Three capacitors in parallel combination |
\[{{C}_{eq}}=3+3+3=9\mu F\] |
(iii) Two capacitors in parallel and one is in series |
\[{{C}_{eq}}=2\mu F\] |
Two capacitors in series and one is in parallel |
\[{{C}_{eq}}=4.5\mu F\] |
