Which element is responsible for damping in the circuit?
In RLC circuit, the presence of resistor causes these oscillation s to die out over period of time and it is called as the damping effect of resistor.
What is resonance frequency in RLC circuit?
The resonant frequency of the series RLC circuit is expressed as. fr = 1/2π√(LC) At its resonant frequency, the total impedance of a series RLC circuit is at its minimum. It also means that the current will peak at the resonant frequency as both inductor and capacitor appear as a short circuit.
What is the quality factor in a RLC circuit?
The Q factor or quality factor shows the quality of the RLC circuit. While designing a RLC circuit, one should aim to achieve the higher Q-factor. Below is the formula for the Q-factor of a RLC circuit: Q = 1/R * √ (L/C)
What is the use of RLC circuit?
RLC circuits have many applications as oscillator circuits . Radio receivers and television sets use them for tuning to select a narrow frequency range from ambient radio waves. In this role, the circuit is often referred to as a tuned circuit. An RLC circuit can be used as a band-pass filter, band-stop filter, low-pass filter or high-pass filter. The tuning application, for instance, is an example of band-pass filtering.
How does a RLC circuit work?
In RLC circuit, the most fundamental elements like resistor, inductor and capacitor are connected across a voltage supply. All these elements are linear and passive in nature; i.e. they consume energy rather than producing it and these elements have a linear relationship between voltage and current.
What is the current in RLC circuit at resonance?
In series RLC circuit current, I = V / Z but at resonance current I = V / R, therefore the current at resonant frequency is maximum as at resonance in impedance of circuit is resistance only and is minimum. The above graph shows the plot between circuit current and frequency. Jun 8 2019
