Find an expression for iL(t) in the circuit of Fig. 9.27, valid for t = > 0, if UC(0-) 10 V and iL(0-) = 0. Note that although it is not helpful to apply Thévenin techniques in this instance, the action of the dependent source links uc and it such that a first- order linear differential equation results.
