32.  In the figure shown, the capacitor is initially uncharged. Which one of the following expressions  describes the current I(t) (in mA) for t > 0?

(A) \(I(t)={5\over3}(1-e^{-{t\over \tau}}), \tau={2\over3} msec\)

(B) \(I(t)={5\over2}(1-e^{-{t\over \tau}}), \tau={2\over3} msec\)

(C) \(I(t)={5\over2}(1-e^{-{t\over \tau}}), \tau={3} msec\)

(D) \(I(t)={5\over2}(1-e^{-{t\over \tau}}), \tau={3} msec\)


Answer-(A) \(I(t)={5\over3}(1-e^{-{t\over \tau}}), \tau={2\over3} msec\)
