If a battery is connected across series combination of a capacitor and a resistor, at t = 0. If at an instant t potential difference across the capacitor be 'V and energy stored in it be U. Then which of the following graph is correct.
A)
B)
C)
D)
Correct Answer:
A
Solution :
[a] \[U=\frac{1}{2}C{{V}^{2}}\]From this, we get \[U=\propto {{V}^{2}}\]
