Why the shape of resonance curve depends on Q of the coil?

Explanation: The shape of the resonance curve depends on the Q factor because of the equation: Q=Resonance frequency / Bandwidth. Sharp resonance means high quality factor. And we know that for high quality factor, resonance frequency should be high(peak should be sharp) and bandwidth should be narrow.

What is an effect of increasing Q in a series resonant circuit?

Increasing Q in a resonant circuit will increase internal voltages and circulating currents, and the resonant circuit will have to be made with components that can withstand these higher voltages and currents. A parameter of a resonant circuit that is related to Q is the half-power bandwidth.

What is Q factor in RLC circuit?

For a parallel RLC circuit, the Q factor is the inverse of the series case: Consider a circuit where R, L and C are all in parallel. The lower the parallel resistance, the more effect it will have in damping the circuit and thus the lower the Q. This is useful in filter design to determine the bandwidth.

What is resonance Q?

The Q, or quality, factor of a resonant circuit is a measure of the “goodness” or quality of a resonant circuit. A practical application of “Q” is that voltage across L or C in a series resonant circuit is Q times total applied voltage.

What is the Q-factor of a coil?

Quality factor (Q) or coil Q-factor is a dimensionless unit for the losses of a coil, quartz, or a resonator. For coils this refers to the ohmic losses of the coil-wire. They are inversely proportional for the coil quality and are calculated from the ratio of reactance to ohmic resistance.

What is Q factor in series resonance circuit?

Q factor of series resonant circuit is defind as the ratio of the voltage developed across the inductance or capacitance at resonance to the impressed voltage, which is the voltage applied across R. Q is inversely proportional to R. So, if R increases Q factor of circuit decreases or if R decreases Q increases.

What is the Q value of the circuit?

Hint: The quality factor or ‘Q’ is a dimensionless quantity that describes the nature of damping in a resonating circuit. It is indeed the ratio of maximum energy stored in the circuit to the energy dissipated during each cycle of oscillation. of its peak value i.e. current is it’s 1√2times of its peak.
