Differbetween
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 current magnification in parallel RLC circuit?
Current flowing through Capacitor
Substitute the value of V in the above equation. 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.
Why parallel resonance is called current resonance?
Answer: Explanation: As a parallel resonance circuit only functions on resonant frequency, this type of circuit is also known as an Rejecter Circuit because at resonance, the impedance of the circuit is at its maximum thereby suppressing or rejecting the current whose frequency is equal to its resonant frequency.
How do you find the current in a parallel RLC circuit?
Phasor Diagram for a Parallel RLC Circuit
We can therefore use Pythagoras's theorem on this current triangle to mathematically obtain the individual magnitudes of the branch currents along the x-axis and y-axis which will determine the total supply current IS of these components as shown.
Why current is maximum in series resonance?
In series RLC circuit current, I = V / Z but at resonance current I = V / R, therefore the current at resonant frequency is maximum as at resonance in impedance of circuit is resistance only and is minimum. ... At starting, when the frequency increases, the impedance Zc decreases and hence the circuit current increases.
How do you fix a resistor and capacitor in parallel?
Ohm's Law for AC circuits: E = IZ ; I = E/Z ; Z = E/I. When resistors and capacitors are mixed together in parallel circuits (just as in series circuits), the total impedance will have a phase angle somewhere between 0° and -90°. The circuit current will have a phase angle somewhere between 0° and +90°.
What is the 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.
What is the condition of resonance?
Resonance occurs in a series circuit when the supply frequency causes the voltages across L and C to be equal and opposite in phase. Thus far we have analysed the behaviour of a series RLC circuit whose source voltage is a fixed frequency steady state sinusoidal supply.
What is the condition of parallel resonance?
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.
What does resonance mean?
1a : the quality or state of being resonant. b(1) : a vibration of large amplitude in a mechanical or electrical system caused by a relatively small periodic stimulus of the same or nearly the same period as the natural vibration period of the system.
What is the power factor at resonance in RLC parallel circuit?
2 Answers. The power factor at resonance in R-L- C parallel circuit is unity.
What is the power factor of RC parallel circuit?
Parallel RC Circuit Power Factor
| E | PF | |

| R | 440 V | |
| C | 440 V | |
| Total | 440 V | 87.3 % |
What is LCR parallel circuit?
Consider a RLC circuit in which resistor, inductor and capacitor are connected in parallel to each other. This parallel combination is supplied by voltage supply, VS. ... That is why parallel RLC circuit is said to have dual relationship with series RLC circuit.
