Hi all,

I tried to solve this, but I can't find the R(equal). I use the following method.

For t<0 the switch is closed so the iL(0-)=4 A

For t>0 it opens and the iL(∞)=0 A

Now, I want to find the value τ=L/R(equal)

Then I will use the:

And finally VL(t) = L * [ ∂iL(t) / ∂t ] which is the Vo

What do you suggest ?Thanks.

**The circuit:**

For t<0 the switch is closed so the iL(0-)=4 A

For t>0 it opens and the iL(∞)=0 A

Now, I want to find the value τ=L/R(equal)

Then I will use the:

**iL(t) = iL(∞) + ( iL(0-) - iL(∞) )* ( e^(-(t/τ) ) )**And finally VL(t) = L * [ ∂iL(t) / ∂t ] which is the Vo

What do you suggest ?Thanks.
