i₁(t) for t > 0 is given by

2.5 - 2.5e^-2t

2.5 - 1.25e^-2t

1.25 - 1.25e^-2t

None of these

Answer : Option B

Explanation :

The time constant t is given by

As R_eq = 4 || 4 = 2 Ω

∴ i₁(t) = i_F - (i_F - i₁)e^-t/t

i_final = = 2.5 A

∴ i₁(t) = 2.5 - (2.5 - 1.25)e^-t/1/2

i₁(t) = 2.5 - 1.25e^-2t.
