Homework Statement
L is a perfect inductor with inductance L. The switch is turned on at t=0 and the currents i1 and i2 run trhough the circuit as indicated by the figure.
Homework Equations
Given this circuit I need to find i1 and i2 for t=0 and t => infinity.
The Attempt at a Solution
For i1 i figure it is simply an LR circuit so we can use the following:
\begin{equation}
I(t) = \frac{V}{R}(1 - e^{-\frac{Rt}{L}})
\end{equation}
Which becomes:
\begin{equation}
i_{1}(t) = \frac{\mathcal{E}}{R_0 + R_1}(1 - e^{-\frac{(R_0 + R_1)t}{L}})
\end{equation}
for t=0 i1 = 0 and for t => infinity i1 => E/(R0 + R1)
i2 is constant and is:
\begin{equation}
i_{2} = \frac{\mathcal{E}}{R_0 + R_2}
\end{equation}
Is this correct?
