What is parallel resonance in RLC circuit?
Resonance occurs in a parallel RLC circuit when the total circuit current is “in-phase” with the supply voltage as the two reactive components cancel each other out. At resonance the admittance of the circuit is at its minimum and is equal to the conductance of the circuit.
How does parallel resonance magnifies the current?
By means of the parallel resonant circuit, the current taken from the supply can be magnified. This type of resonance is called current resonance. Quality factor of R-L-C parallel circuit is the current magnification in the circuit at resonance.
What is the resonant frequency of parallel RLC circuit?
Parallel RLC Circuit Resonance – Basically, parallel resonance occurs when XC = XL. The frequency at which resonance occurs is called the resonant frequency. When XC = XL, the two branch currents are equal in magnitude and 180° out of phase with each other.
What is series and parallel RLC circuit?
In parallel RLC Circuit the resistor, inductor and capacitor are connected in parallel across a voltage supply. The parallel RLC circuit is exactly opposite to the series RLC circuit. The applied voltage remains the same across all components and the supply current gets divided.
What is the condition for 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.
When impedances are in parallel they carry the same?
For components connected in parallel, the voltage across each circuit element is the same; the ratio of currents through any two elements is the inverse ratio of their impedances.
Why current is minimum in parallel resonance?
Hence the current at this condition is maximum. In parallel RLC circuit, at resonance condition admittance is purely resistive and it is equal to R. It is the minimum admittance or maximum impedance condition. Hence the current at this condition is minimum.
What happens parallel resonance?
How do you find the resonance frequency of a parallel circuit?
Frequency at Resonance Condition in Parallel resonance Circuit. The value of inductive reactance XL = 2πfL and capacitive reactance XC = 1/2πfC can be changed by changing the supply frequency. As the frequency increases, the value of XL and consequently the value of ZL increases.
