In the circuit in the figure, the switch S is closed at t = 0. Assuming that there is no initial charge in the capacitor, the current ic(t) for t > 0 is
1
\(\frac{V_s}{R}e^{\frac{-2t}{RC}}A\)
2
\(\frac{V_s}{R}e^{\frac{-t}{RC}}A\)
3
\(\frac{V_s}{2R}e^{-\frac{2t}{RC}}A\)
4
\(\frac{V_s}{2R}e^{\frac{-t}{RC}}A\)
