Explanation / Answer

(A) T = L/R

and I = e/R [1 - e^(-t/T)]

I = e/R [ 1 - e^(-tR/L)]

Ans(1st option)

(b) Counterclock wise

(c) I = (1.5/49)[1 - e^(-0.1 x 49/3.4)]

I = 0.0234 A

(d) I = (1.5/49)[1 - e^-1] = 0.0194 A

(e) then I = 1.5/49 =0.0306 A

(f) I = (e/R) [e^(-tR/L)]

(g) counterclockwise

(h) I = 7.24 x 10^-3 A

(i) I = 0.0113 A

(j) I = 0
