GATE EC 2014: RC Circuit Current I(t) Transient Analysis (Uncharged Capacitor)

```

EC > GATE 2014 SET-2 > Transient Analysis

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) = (5/3)(1 - e^-t/τ), τ = 2/3 msec

B

I(t) = (5/2)(1 - e^-t/τ), τ = 2/3 msec

C

I(t) = (5/3)(1 - e^-t/τ), τ = 3 msec

D

I(t) = (5/2)(1 - e^-t/τ), τ = 3 msec

Correct : a
