the net oppostion offered by the rlc circuit for the ac current to pass through it is called the impedance of rlc circuit
AnswerThe impedance of an RLC circuit is the vector sum of the circuit's resistance, inductive reactance, and capacitive reactance, expressed in ohms.

∙ 12y ago-- With a DC applied across the series RLC, the impedance is infinite,
because a capacitor doesn't pass DC at all.
-- With an AC applied across the RLC, the magnitude and angle of the
impedance both depend on the frequency of the applied AC.
AnswerFor an a.c. system, the impedance is the vector sum of the resistance, inductive reactance, and the capacitive reactance. It can also be found be dividing the supply voltage by the load current.

Why does series rlc circuit provides voltage magnification at resonance?
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.

Will the impedance in a series RL circuit increase as the frequency decreases?
When the frequency of Parallel RL Circuit Increases,XL increases which causes IL (current through inductor) decreases. Decrease in IL causes It (It=Il+Ir) to decrease,which means by relation IT=Vs/Zt ,the Zt (Total Impedance) Increases.
Does resonant frequency of RLC series circuit depends on Resistance?
No, the resonant frequency of a RLC series circuit is only dependant on L and C. R will be the impedance of the circuit at resonance.
What is Impedance for an RLC circuit in series?
1. The RLC series circuit is a very important example of a resonant circuit. It has a minimum of impedance Z=R at the resonant frequency, and the phase angle is equal to zero at resonance.AnswerThe impedance of an RLC circuit is the vector sum of the circuit's resistance, inductive reactance, and capacitive reactance -all of which are expressed in ohms. This applies whether the circuit is at resonance or not.
Does the impedance of a parallel RLC circuit equal to the value of the resistor?
No. You have to consider the inductor and the capacitor. Impedance of RLC circuit is equal to to the Value of Resistor Only AND Only on Resonate frequency. otherwise u have to cnsider resistance inductance and capacitance together in series.
What is q factor in rlc series circuit?
In a RLC series circuit the Q factor magnify the voltage to the circuit.

A circuit in which elements are connected in series.For example in RLC series circuit resistor,inductor and capacitor are connected in series.
Do you expect angle in rlc series circuit to be a constant?
The phase shift angle of an RLC circuit is constant for a constant frequency, but changes with different frequencies.The phase angle of the AC in the RLC circuit is however continuously changing. Otherwise it wouldn't be AC.

Why LCR series circuit is called acceptor circuit?
Answer:A given combination of R,L and C in series allows the current to flow in a certain frequency range only.For this reason it is known as an acceptor circuit i.e.,it accepts some specific frequencies....
What is single tuned amplifiers and what is the hybrid equivalent circuit and how to analyze?
either we have to use a series or parallel RLC circuit to make the circuit tunable either at base or at collector. in series tuned amplifier an input impedance is only due to load resistance and net impedance due to capacitor and inductor is zero, so a huge amount of current flow through the circuit and almost all input all voltage appears across load resistance. so maximum gain is possible in series tuned amplifier. sudhanshu kumar siliguri institute of tech. b-tech, 2nd year, (ECE)
