IN A SERIES RLC CIRCUIT XL=XC.THEREFORE, IMPEDANCE Z IS MINIMUM AND Z=R.SINCE THE IMPEDANCE IS MINIMUM,CURRENT IN THE CIRCUIT WILL BE MAXIMUM. XL=XC MULTIPLYING BY MAX. CURRENT Io (AT RESONANCE) ON BOTH SIDES, WE GET, IoXL=IoXC I.E. Vlo=Vlc(POTENTIAL DIFFERENCE ACROSS INDUCTANCE IS EQUAL TO THE POTENTIAL DIFFERENCE ACROSS CAPACITANCE AND BEING EQUAL AND OPPOSITE THEY CANCEL EACH OTHER.)SINCE Io IS MAXIMUM,Vlo AND Vco WILL ALSO BE MAXIMUM.THUS,VOLTAGE MAGNIFICATION TAKES PLACE DURING RESONANCE.HENCE,IT IS ALSO REFERRED TO AS VOLTAGE MAGNIFICATION CIRCUIT.

Why series resonance is called voltage resonance?

Series resonance isn't generally referred to as 'voltage resonance', but the expression probably comes from the fact that, at resonance, the voltage drop across the inductive component of a circuit is exactly equal to the voltage drop across the capacitive component of the circuit and, if the resistance of the resonant circuit is low in comparison with its reactance, then each of these voltage drops can be significantly higher than the supply voltage.


What is the power factor on a circuit in resonance?

You are presumably referring to an 'R-L-C' circuit. At resonance, the load current is in phase with the supply voltage and, so, the power factor is unity.


How does the non inverting amplifier differs from voltage follower circuit?

altough voltage follower circuit provides output voltage which is in phase to input voltage as in noninverting amplifier but in unamplified form.


What is need of voltage follower circuit?

It's a buffer circuit - it provides a high impedance input, and low impedance output with ~ unity gain. If you have a circuit that cannot drive much power, you can use a voltage follower to help. Also, if the input or output of a circuit needs to stay a specific value, such as with filters, you can easily control this due to the isolation the voltage follower provides.


What happens in series resonance?

The properties of a series alternating-current L-R-C circuit at resonance are:the only opposition to current flow is resistance of the circuitthe current flowing through the circuit is maximumthe voltage across the resistive component of the circuit is equal to the supply voltagethe individual voltages across the inductive and capacitive components of the circuit are equal, but act in the opposite sense to each otherthe voltage appearing across both the inductive and capacitive components of the circuit is zeroif the resistance is low, then the individual voltages appearing across the inductive and capacitive components of the circuit may be significantly higher than the supply voltage

Why you use parallel resonance circuit instead of series resonance circuit in tuned voltage amplifier?

At resonance...a parallel tank circuit matches the applied sine voltage so close that there is almost 0 current flow from the source...i.e., max impedance at resonance...the capacitor and inductor are swapping energy with each other in tune with the source... visualize it...in order to have 0 current flow for an incoming varying voltage...that would mean that the tank voltage would be varying exactly at the same frequency and voltage! Thus...you have effectively "tuned" into a voltage which would be critical in 'tuned' voltage amplifier... A series resonant circuit does not tune into a voltage...in fact at resonance the voltage across the inductor capacitor will be 0!...a short or minimum impedance condition Of course my discussion assumed ideal components...in the real world there will be 'stray' resistances which will alter the results in magnitude to the size of the resistance... Hope this helps


In a series RLC circuit at frequencies above resonance is the circuit capacitive or inductive?

in series you XL, voltage leads the current, and in Parallel current leads the voltage. so your answer should reflect on this theory.

What is driven RL circuit?

A driven RL circuit is a circuit that contains a resistor (R) and an inductor (L) connected in series with an external source of alternating current (AC) or voltage. The external source provides energy to the circuit, driving the current through the inductor and resistor. This circuit can exhibit interesting behavior such as resonance and phase shifts due to the interplay between the inductive and resistive components.
