Chapter 7, Problem 7.11(choose chapter or problem)
In the circuit in Fig. P7.10, let \(I_{g}\) represent the dc current source, \(\sigma\) represent the fraction of initial energy stored in the inductor that is dissipated in \(t_{o}\) seconds, and L represent the inductance.
a) Show that
\(R=\frac{L \ln [1 /(1-\sigma)]}{2 t_{o}}\).
b) Test the expression derived in (a) by using it to find the value of R in Problem 7.10.
