The RL parallel circuit is a first-order circuit because it’s described by a first-order differential equation, where the unknown variable is the inductor current i(t). A circuit containing a single equivalent inductor and an equivalent resistor is a first-order circuit. bulgarian power burst training pdf differential equation to determine the values of K1 and s . (Alternatively, we can determine K1 by solving the circuit in steady state as discussed in Section 4.2.) 5. Use the initial conditions to determine the value of K2. 6. Write the final solution.

- 7. Introduction and Chapter Objectives First order systems are, by definition, systems whose input-output relationship is afirst orderdifferential equation. A first order differential equation contains afirst order derivativebut no derivative higher than first order–the order of a differential equation is the order of the highest order derivative present in the equation.
