Consider the circuit shown in Figure P 8.3-25a and corresponding plot of the voltage
Chapter 8, Problem P8.3-25(choose chapter or problem)
Consider the circuit shown in Figure P 8.3-25a and corresponding plot of the voltage across the \(40-\Omega\) resistor shown in Figure P 8.3-25b. Determine the values of L and \(R_2\).
Hint: Use the plot to determine values of D, E, F, and a such that the voltage can be represented as
\(v(t)=\left\{\begin{array}{l} D \text { for } t<0 \\ E+F e^{-a t} \text { for } t>0 \end{array}\right.\)
