A) half the charge of the\[1\,\,\mu F\]capacitor
B) twice the charge of the \[1\,\,\mu F\]capacitor
C) twice the potential difference of the \[1\,\,\mu F\]capacitor
D) half the potential difference of the \[1\,\,\mu F\]capacitor
Correct Answer: B
Solution :
(b) twice the charge of the \[1\,\,\mu F\]capacitor \[{{q}_{1}}:{{q}_{2}}={{C}_{1}}:{{C}_{2}}\] \[{{q}_{1}}:{{q}_{2}}=2:1\] \[{{q}_{1}}=2{{q}_{2}}\] Thus, \[20\,\mu F\]capacitor has twice the charge of \[10\,\mu F\]capacitor.You need to login to perform this action.
