Question

Answer

Quality factor is the ratio of reactance to resistance. voltage magnification ratio is the voltage across reactance to that of voltage across resistance. so they are proportional since it's a ratio they will be same.

Answer

Quality factor is also known as voltage magnification because the voltage across the capacitor or inductor in resonance condition is equal to Q times the source voltage.

Answer

Quality factor is also known as Voltage magnification because it represents the ratio of the voltage across a reactive component (such as an inductor or capacitor) to the applied voltage. In other words, it quantifies the amplification of voltage across the reactive component in a resonant circuit.

The quality factor (Q) is a dimensionless parameter that is defined as the ratio of the reactance of the reactive component to the resistance of the circuit. It is given by the formula:

Q = X/R

where X is the reactance of the component and R is the resistance of the circuit. The reactance is the opposition offered by the component to the flow of alternating current and is dependent on the frequency of the signal.

The quality factor is a measure of the selectivity or sharpness of resonance in a circuit. A higher quality factor indicates a circuit with a narrow bandwidth and a sharper resonance peak, while a lower quality factor indicates a circuit with a wider bandwidth and a broader resonance peak.

The voltage magnification in a resonant circuit is directly related to the quality factor. A higher quality factor implies a higher voltage magnification, meaning that the voltage across the reactive component is amplified compared to the applied voltage. This is because a higher quality factor indicates a lower resistance in the circuit, which allows more energy to be stored in the reactive component and results in a higher voltage across it.

On the other hand, a lower quality factor implies a lower voltage magnification, meaning that the voltage across the reactive component is attenuated compared to the applied voltage. This is because a lower quality factor indicates a higher resistance in the circuit, which dissipates more energy and results in a lower voltage across the reactive component.

In summary, the quality factor is also known as voltage magnification because it represents the amplification or attenuation of voltage across a reactive component in a resonant circuit. It is directly related to the ratio of the reactance to the resistance in the circuit and determines the selectivity and sharpness of resonance.
