What is series resonance and parallel resonance?
Series resonance refers to the resonance that occurs in circuits where capacitors and inductors are connected in series , whereas parallel resonance refers to the resonance that occurs in circuits where the capacitors and inductors are connected in parallel.
What are the properties of parallel resonance circuit?
A parallel resonant circuit stores the circuit energy in the magnetic field of the inductor and the electric field of the capacitor . This energy is constantly being transferred back and forth between the inductor and the capacitor which results in zero current and energy being drawn from the supply.
What is the use of series and parallel resonance?
Chapter 6 – Resonance
One use for resonance is to establish a condition of stable frequency in circuits designed to produce AC signals . Usually, a parallel (tank) circuit is used for this purpose, with the capacitor and inductor directly connected together, exchanging energy between each other.
What are the characteristics of series resonance?
(1) The current is maximum at the resonant frequency . (2) The current is in phase with the generator voltage, or the phase angle of the circuit is . (3) The voltage is maximum across either and alone. (4) The impedance is minimum at equal only to the low .
What do you mean by parallel resonance?
Parallel resonance is a resonance condition that usually occurs in parallel resonant circuits, where the voltage becomes a maximum for a given current. Being a parallel resonance means the impedance is high and inrush surge current relatively low compared to a simple capacitor .
What are the applications of resonance?
- 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.
Why is resonance a bad thing?
It may cause violent swaying motions and potentially catastrophic failure in improperly constructed structures including bridges, buildings and airplanes . This is a phenomenon known as resonance disaster.
What do you mean by resonance?
This is known as resonance – when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion . The word resonance comes from Latin and means to “resound” – to sound out together with a loud sound.
What is difference between series and parallel connection?
In a series circuit, all the components are arranged in a single line. In a parallel circuit, all the components are arranged parallel to each other. If more than one resistor is connected in series, the voltage across each resistor is not the same though the current flow is the same throughout the circuit.
What are the important features of LCR series resonance?
The high value of current at resonance produces very high values of voltage across the inductor and capacitor. Series resonance circuits are useful for constructing highly frequency selective filters. However, its high current and very high component voltage values can cause damage to the circuit.
What is Q factor in LCR circuit?
Q-factor: In LCR Circuit, the ratio of resonance frequency to the difference of its neighbouring frequencies so that their corresponding current is 1/2 times of the peak value, is called Q-factor of the circuit.
What is the resonance condition?
resonance: In an electrical circuit, the condition that exists when the inductive reactance and the capacitive reactance are of equal magnitude , causing electrical energy to oscillate between the magnetic field of the inductor and the electric field of the capacitor.
What is resonant frequency formula?
The frequency where both parameters overlap is known as the resonant frequency of an RLC circuit. Therefore, the resonant frequency can be derived by expressing the equal value of both capacitive and inductive reactance as follows: X L = X . C .
Which values decreases in parallel resonance?
As a result, there is a decrease in the magnitude of current I 2 and this I 2 current lags behind the voltage V. On the other hand, the value of capacitive reactance decreases and consequently the value of I C increases. At some frequency, f r called resonance frequency.
What is Q factor in physics?
In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. ... Q factor is alternatively defined as the ratio of a resonator's centre frequency to its bandwidth when subject to an oscillating driving force.
