In the circuit shown, in switch S is open for a long time and is closed at t = 0. The current i(t) for t ≥ 0⁺ is

i(t) = 0.5 - 0.125e^-1000t A

i(t) = 1.5 - 0.125e^-1000t A

i(t) = 0.5 - 0.5e^-1000t A

i(t) = 0.375e^-1000t A

Answer: Option

Explanation:

i(f) = 0.5, i(i) = 0.75

i(t) = V_r + (i_i - i_j)e^-1/p = 0.5 - 0.125e^-1000t .
