The characteristic equation usually takes the form of a quadratic equation, and it has two roots s 1 and s 2. , the resistor. Understanding Differential Equations in Electrical Circuits Now, don’t let the term “differential equation” scare you off. The circuit for the RLC natural response. A generalized model of an n-stage cascaded RLC network with time delays is oped using the Caputo fractional derivative. If you know the transient response (the general solution) of the circuit, you can work backward to determine the specific component values or the driving forces that govern its behavior. No credits will be given for partial solutions. Taking the Laplace transform of our differential equation and solving for we get Text solution Verified Introduction We apply the Laplace transform to convert time‐domain circuit equations into algebraic s‐domain forms, solve for circuit responses including transients and steady‐state, then invert back to t‐domain.
