A) 10 \[\Omega C\]
B) 5\[\Omega C\]
C) 6\[\Omega C\]
D) 10.2 \[\Omega C\]
Correct Answer: A
Solution :
We know that capacitor offers infinite resistance for DC source. Current taken from the cell \[i=\frac{E}{R+r}\] \[\therefore \] \[i=\frac{2.5}{1+1+0.5}=1\,\,A\] Potential drop across capacitor \[V=E-ir\] \[=2.5-1\times 0.5=2\,\,V\] The current in\[2\Omega \]resistor is zero. Charge on capacitor \[Q=CV\] \[=5\times 2=10\mu C\]You need to login to perform this action.
