Homework Statement
For the circuit shown below, the current through the inductor is defined as follows:
[tex]
i(t)=\begin{cases}
0 & \text{if } -\infty <t<0 \\
1-e^{-2t}& \text{if } 0\leq t < \infty
\end{cases}
[/tex]
L = 1H, R2 = 2 ohms
For t=> 0 find:
a) VL(t)
b) Vr(t)
c) V1(t)
d) Power absorbed by the inductor
Homework Equations
[tex]
i(t)=\frac{v}{R}(1-e^{-Rt/L})
[/tex]
The Attempt at a Solution
As t goes to infinity, current goes to 1A and the inductor becomes a wire. So V1 = 2V
But i don't think this is what it is asking for.
From the relevant equation section, solving for V would leave only 2
W = 0.5Li^2
W = 0.5(1)(1-e^{-2t})^2
Vr = (1-exp(-2t))/2
Vl = 0V
