How can you differentiate between the natural responce rlc circuit and step response rlc circuit?

The natural response of an RLC circuit refers to how the circuit behaves when it is allowed to evolve from an initial state without any external inputs, typically characterized by the transient response due to the circuit's inherent inductance, capacitance, and resistance. In contrast, the step response of an RLC circuit describes how the circuit reacts to a sudden change in voltage or current, such as applying a step input, leading to a transient response followed by a steady-state behavior. While the natural response focuses on the circuit's intrinsic properties, the step response emphasizes the circuit's behavior under specific external conditions.
