A) \[\frac{C\varepsilon }{3}\]
B) \[\frac{C\varepsilon }{2}\]
C) \[\frac{C\varepsilon }{4}\]
D) \[C\varepsilon \]
Correct Answer: D
Solution :
\[{{I}_{\max }}=\frac{2\varepsilon }{R}\] at \[t=0\] |
\[I=\frac{\varepsilon }{R}\] at \[t=\infty \] |
so charge on the capacitor is \[C\varepsilon ,\] when current is 50% of maximum current. |
