What are the effects on the circuit when series resonance occurs?

The series resonant circuit has the ability to absorb heavy current and power from the mains. From this, it is clear that at resonance, the opposition to the flow of current is only provided by resistance. At this condition, the circuit draws the maximum current.

What is resonance in series RLC circuit?

Series Resonance 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 sharpness of the minimum depends on the value of R and is characterized by the “Q” of the circuit.

What is the significance of resonance in electrical circuit?

At resonance, the series impedance of the two elements is at a minimum and the parallel impedance is at maximum. Resonance is used for tuning and filtering, because it occurs at a particular frequency for given values of inductance and capacitance.

What is the impedance of a RLC circuit?

RLC Series 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 is the formula for parallel resonance?

The resonant frequency of a parallel circuit is the frequency at which the sum of the two “reactive” components becomes equal to zero. Thus at the resonant frequency the circuit becomes purely resistive as Zp = R – j(XL – Xc) = R.

What is parallel resonance circuit?

Parallel resonance occurs when the supply frequency creates zero phase difference between the supply voltage and current producing a resistive circuit. In many ways a parallel resonance circuit is exactly the same as the series resonance circuit we looked at in the previous tutorial.

How to determine resonant frequency?

The formula for resonant frequency for a series resonance circuit is given as f = 1/2π√ (LC)
