Damping factor (RLC circuit)

Description

Damping is an influence within or upon an oscillatory system that has the effect of reducing, restricting or preventing its oscillations.( The neper frequency, or attenuation is a measure of how fast the transient response of the circuit will die away after the stimulus has been removed)
Damping is caused by the resistance in the circuit. It determines whether or not the circuit will resonate naturally. Circuits which will resonate in this way are described as underdamped and those that will not are overdamped. The value of the damping factor determines the type of transient that the circuit will exhibit.
