Transient Analysis of Electric Circuits Using Laplace Transform
In electrical engineering, a transient response or natural response is the electrical response of a system to a change from equilibrium.
The condition prevailing in an electric circuit between two steady-state conditions is known as the transient state; it lasts for a very short time. The currents and voltages during the transient state are called transients.
In general, transient phenomena occur whenever
- a circuit is suddenly connected or disconnected to/from the supply,
- there is a sudden change in the applied voltage from one finite value to another,
- a circuit is short-circuited.
We consider the transient analysis for the following circuits subject to step input, impulse input and sinusoidal input:
- RL Series Circuit,
- RC Series Circuit,
- RLC Series Circuit, and
- RLC Parallel Circuit.
