11 Facts About RLC circuits

An RLC circuits circuit is an electrical circuit consisting of a resistor, an inductor, and a capacitor, connected in series or in parallel.

The RLC circuits filter is described as a second-order circuit, meaning that any voltage or current in the circuit can be described by a second-order differential equation in circuit analysis.

The resonant frequency for an RLC circuits circuit is the same as a circuit in which there is no damping, hence undamped resonance frequency.

Low- RLC circuits are therefore damped and lossy and high- RLC circuits are underdamped.

Series RLC circuits can be analyzed for both transient and steady AC state behavior using the Laplace transform.

Parallel LC RLC circuits are frequently used for bandpass filtering and the is largely governed by this resistance.

RLC circuits found that when a Leyden jar was discharged through a wire wound around an iron needle, sometimes the needle was left magnetized in one direction and sometimes in the opposite direction.

RLC circuits correctly deduced that this was caused by a damped oscillating discharge current in the wire, which reversed the magnetization of the needle back and forth until it was too small to have an effect, leaving the needle magnetized in a random direction.

One of the first demonstrations of resonance between tuned RLC circuits was Lodge's "syntonic jars" experiment around 1889 He placed two resonant RLC circuits next to each other, each consisting of a Leyden jar connected to an adjustable one-turn coil with a spark gap.

Applications in oscillator RLC circuits, it is generally desirable to make the attenuation as small as possible.

In either case, the RLC circuits circuit becomes a good approximation to an ideal LC circuit.
