A series resonance circuit is also known as an Acceptor Circuit because at resonance, the impedance of the circuit is at its minimum, so it easily accepts the current whose frequency is equal to its resonant frequency. This type of circuit only functions on resonant frequency.
The variations of a series resonant circuit include the example in Serway & Beichner. The smaller the resistance, the higher the 'Q' for given values of L and C. The parallel resonant circuit is more commonly used in electronics, but the algebra necessary to characterize the resonance is much more involved.
In a series resonant circuit, the voltage across the resistor is equal to the supply voltage, i.e., V = V_r. In a series RLC circuit, the current I = V / Z, but at resonance, I = V / R. Therefore, the current at the resonant frequency is maximum, as at resonance, the impedance of the circuit is just the resistance.
The series resonant frequency, f0, is the frequency at which the magnitudes of the inductive and capacitive reactances are equal. This implies that the power factor is unity at resonance. Also, in a real world circuit R is the combination of the series resistance plus any resistance from the inductor's coil.
In a series LC circuit, the resonant frequency is the frequency at which the total impedance becomes purely 'real', meaning there are no imaginary impedance components. This occurs when the circuit acts as a short circuit, with only the resistance, R, opposing current flow.
This action is not available. This exercise investigates the voltage relationships in a series resonant circuit. Of primary importance are the establishment of the resonant frequency and the quality factor, or Q, of the circuit with relation to the values of the R, L, and C components.
X L and X C are 180 degrees out of phase.; X L and X C are equal in value (100 Ω), resulting in a net reactance of zero ohm.; The only opposition to current is then R (10 Ω). Z is equal to R and is at its minimum value, allowing the greatest amount of current to flow. Figure 1 Impedance vector for a series RLC resonant circuit..

Instead of analysing each passive element separately, we can combine all three together into a series RLC circuit. The analysis of a series RLC circuit is the same as that for the dual series R L and R C circuits we looked at previously, except this time we need to take into account the magnitudes of both X L and X C to find the overall circuit reactance. . Series RLC circuits are …

If we consider an example of a series resonant circuit. At resonance, the reactances cancel out leaving just a peak voltage, Vpk, across the loss resistance, R. Thus, Ipk = Vpk/R is the maximum current which passes through all elements. Then, In terms of the series equivalent network for a capacitor shown above, its Q is given by:
In a series resonance circuit, the inductor (L) and capacitor (C) are connected in series, along with a resistor (R). The resonant frequency (f₀) is the frequency at which the inductive and capacitive reactance cancel each other out, resulting in a minimum impedance. During this point the circuit becomes highly responsive to the applied ...
Series resonance is formed by both inductive and capacitive reactance in series. Equivalent system impedance becomes series with utility power supply, transformers, and capacitors/filters. Series resonance provides a low impedance path to harmonic currents and results in unexpected harmonic current flow through the system equipment [12] is called current amplification in the …
Series LC resonant circuit with resistance in parallel with L. Maximum current at roughly 178.9 Hz instead of 159.2 Hz! Series resonant circuit with resistance in parallel with L shifts maximum current from 159.2 Hz to roughly 180 Hz. And finally, a series LC circuit with the significant resistance in parallel with the capacitor (figure below).
Hence, at the series resonance condition, the circuit offers minimum impedance. Consequently, the value of electric current flowing through the circuit will be maximum. The series resonance results in the maximum admittance in the series RLC circuit. Some common applications of series resonance are −. Oscillator circuits; Voltage amplifiers

Two-element circuits and uncoupled RLC resonators. RLC resonators typically consist of a resistor R, inductor L, and capacitor C connected in series or parallel, as illustrated in Figure 3.5.1. RLC resonators are of interest because they behave much like other electromagnetic systems that store both electric and magnetic energy, which slowly dissipates due to resistive …
Effects of series resonance. When series resonance occurs, the impedance of the circuit is minimum and is equal to the resistance of the circuit. As a result of this, the current in the circuit becomes maximum. This is shown in the resonance curve drawn between current and frequency (Figure 4.54). At resonance, the impedance is
