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.
How do you measure time constant of RLC circuit?
Measurement of the Time Constant in an RC Circuit Procedure: Using your oscilloscope, measure the square-wave output from the function generator. ... Method #1. The first way to measure the τ is to read R & C directly off of the components themselves. ... Method #2. Connect your oscilloscope to measure the voltage across the capacitor. ... Method #3. The final way of measuring τ is to take data at many points. ...
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 role of resistance in a RLC circuit?
Friction will slowly bring any oscillation to a halt if there is no external force driving it. Likewise, the resistance in an RLC circuit will "damp" the oscillation, diminishing it with time if there is no driving AC power source in the circuit.

The characteristic equation is quadratic and thus has two roots. The roots may be 1) real and equal, 2) real but unequal or 3) complex conjugates. A series RLC circuit can be modeled as a second order differential equation. When its roots are real and equal, the circuit response to a step input is called “Critically Damped”.
