The properties of a series alternating-current L-R-C circuit at resonance are:
- the only opposition to current flow is resistance of the circuit
- the current flowing through the circuit is maximum
- the voltage across the resistive component of the circuit is equal to the supply voltage
- the individual voltages across the inductive and capacitive components of the circuit are equal, but act in the opposite sense to each other
- the voltage appearing across both the inductive and capacitive components of the circuit is zero
- if 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

What is meant by resonance and explain the series and parallel resonance? by kathiresan

Series resonance
Why series resonance is called voltage resonance?
Series resonance is called voltage resonance because at resonance frequency in a series RLC circuit, the impedance of the inductor and capacitor cancel each other out, resulting in minimum impedance. This causes the total voltage across the circuit to be maximized, leading to a peak in voltage across the components at resonance. This phenomenon is known as voltage resonance because it results in a maximum voltage across the circuit at that specific frequency.
Series resonance circuit is also known as acceptor circuit why?
Because the series resonant circuit has the lowest possible impedance at resonance frequency, thus allowing the AC current to circulate through it. At resonance frequency, XC=XL and XL-XC = 0. Therefore, the only electrical characteristic left in the circuit to oppose current is the internal resistance of the two components. Hence, at resonance frequency, Z = R. Note: This effect is probably better seen with vectors. Clarification: Resonant circuits come in two flavors, series and parallel. Series resonant circuits do have an impedance equal to zero at the resonant frequency. This characteristic makes series resonant circuits especially well suited to be used as basic pass-band filters (acceptors). However, parallel circuits present their maximum impedance at the resonant frequency, which makes them ideal for tuning purposes.
Why does the resistance in a series resonant circuit have no bearing on the resonant frequency?
Series resonance occurs when a circuit's inductive reactance is equal to its capacitive reactance. The resistance of the circuit is irrelevant.WebRep currentVote noRating noWeight
