What is the use of parallel 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 is the importance of series and parallel resonance circuit?

One of the most important circuits used in electrical and electronic circuits is the series resonance circuit that can be found in various forms such as in noise filters, AC mains filters and in radio and television tuning circuits where a very selective tuning circuit for the receiving of different frequency channels …

Why do we need resonance in circuit?

The importance of resonance is that the circuit can either absorb or dissipate the maximum amount of energy at resonance. One practical example is used in a radio receiver. Many the frequencies from different radio stations are impinging on the radio’s antenna at the same time.

What is the difference between parallel and series 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 is parallel circuit known as?

If the resonance occurs in parallel RLC circuit, then it is called as Parallel Resonance. Consider the following parallel RLC circuit, which is represented in phasor domain. Here, the passive elements such as resistor, inductor and capacitor are connected in parallel.

What is difference between series and parallel resonance?

The main difference between series and parallel resonance is that series resonance occurs when the arrangement of the components creates the minimum impedance, whereas parallel resonance occurs when the arrangement of components creates the largest impedance.

Why parallel resonance is called current magnification?

Current flowing through Capacitor Note − Parallel resonance RLC circuit is called as current magnification circuit. Because, the magnitude of current flowing through inductor and capacitor is equal to Q times the input sinusoidal current I.
