6 Chapter 1: Introduction b Assume a steady-state solution iss = B Substituting this into the differential equation yields RB = 1, from which B = 1 R The characteristic equation is LM + R = 0, from which M = - R L Thus, the total solution is i(t) = Ae-(R/L)t + 1 R Solving for the arbitrary constants, i(0) = A + 1 R = 0 Thus, A = - 1 R
