Which are the characteristics of series resonance circuit?

(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 are the characteristic of a series RLC AC circuit?

The RLC series circuit is a very important example of a resonant circuit. It has a minimum of impedance Z=R at the resonant frequency, and the phase angle is equal to zero at resonance.

What does this resonant frequency represent physically?

In sound applications, a resonant frequency is a natural frequency of vibration determined by the physical parameters of the vibrating object. It is easy to get an object to vibrate at its resonant frequencies, hard to get it to vibrate at other frequencies. …

What happens at resonance in LCR series circuit?

In LCR series circuits, resonance occurs when the value of inductive and capacitive reactances have equal magnitude but have a phase difference of $180°$. Thus, they cancel each other. This is known as the resonance frequency of a series LCR circuit.

What are the characteristics of parallel resonant 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.

How the RLC circuit behaves for the frequencies above and below the resonant frequencies?

2. How the RLC series circuit behaves for the frequencies above and below the resonant frequencies. For frequencies below resonant frequency, the capacitive reactance is more than the inductive reactance. Therefore the equivalent reactance is equal to capacitive and the circuit behaves like a RC circuit.
