A) 2250\[V\]
B) 2222\[V\]
C) \[2.25\times {{10}^{6}}V\]
D) \[1.1\times {{10}^{6}}V\]
Correct Answer: B
Solution :
\[\frac{1}{C}=\frac{1}{3}+\frac{1}{6}\] Þ \[C=2\,pF\] Total charge\[=2\times {{10}^{-12}}\times 5000={{10}^{-8}}\,C\] The new potential when the capacitors are connected in parallel is \[V=\frac{2\times {{10}^{-8}}}{(3+6)\times {{10}^{-12}}}=2222\,V\]You need to login to perform this action.
