What is RLC circuit analysis?
R-L-C Circuit Analysis. Objective: To study the behaviour of a series R-L-C circuit. [Fig 1: Sinusoidal input to series RLC circuit] With reference to figure 1, the application of Kirchoff’s law results, V=IR+jIXL+IjωC, Where,VR=IR,VL=jIXL,VC=IjωC.
What will be the response of a series RLC circuit?
In series RLC circuit, there are two energy storing element which are L and C, such a circuit give rise to second order differential equation and hence called second order circuit.
What are RLC parameters?
There are two fundamental parameters that describe the behavior of RLC circuits: the resonant frequency and the damping factor.
What happens in RLC circuit?
The resonance of a series RLC circuit occurs when the inductive and capacitive reactances are equal in magnitude but cancel each other because they are 180 degrees apart in phase. The sharp minimum in impedance which occurs is useful in tuning applications.
What is nature of RLC circuit?
The RLC circuit is representative of real life circuits we actually build, since every real circuit has some finite resistance, inductance, and capacitance. This circuit has a rich and complex behavior. It shows up in many areas of engineering. The mechanical analog of an RLC circuit is a pendulum with friction.
What happens in a RLC circuit?
What happens when an RLC circuit is in resonance?
At resonance in series RLC circuit, both inductive and capacitive reactance cancel each other and we know that in series circuit, the current flowing through all the elements is same, So the voltage across inductor and capacitor is equal in magnitude and opposite in direction and thereby they cancel each other.
What is the use of RLC circuits?
RLC circuits are often used as oscillator circuits because they produce sine waves, square waves, or triangle waves. These are oscillating electronic signals that can convert direct current into alternating current or work as a low-pass filter, high-pass filter, band-stop filter, and band-pass filter.
Why does RLC circuit oscillate?
Once the capacitor is discharged, the inductor resists any change in the current flow, causing the capacitor to be charged again with the opposite polarity. 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.
