How does a RLC circuit work?
RLC Circuit. This is an RLC circuit, which is an oscillating circuit consisting of a resistor, capacitor, and inductor connected in series. The voltage in the capacitor eventually causes the current flow to stop and then flow in the opposite direction. The result is an oscillation, or resonance.
Are RLC circuits used in communication systems?
The resonant RLC circuits have many applications like Oscillator circuit, radio receivers, and television sets are used for the tuning purpose. The series and RLC circuit mainly involves in signal processing and communication system The Series resonant LC circuit is used to provide voltage magnification
What is the quality factor in a RLC circuit?
Parallel RLC Circuit Impedance: Power Factor: Resonance Frequency: When inductive reactance XL & capacitive reactance Xc of the circuit is equal. Quality Factor: It is the ratio of stored energy to the energy dissipated in the circuit. Bandwidth: Resonant Circuit Current: The total current through the circuit when the circuit is at resonance. Current Magnification. ... More items...
What is the Q factor in RLC circuit?
For a parallel RLC circuit, the Q factor is the inverse of the series case: Consider a circuit where R, L and C are all in parallel. The lower the parallel resistance, the more effect it will have in damping the circuit and thus the lower the Q. This is useful in filter design to determine the bandwidth.
