Why is the parallel resonant circuit called an rejector circuit?

∙ 13y ago
THE PARALLEL rlc CIRCUIT IS CALLED A REJECTOR CIRCUIT BECAUSE IT REJECTS DOWN THE CURRENT. THE REASON IS AT RESONANCE THE IMPEDENCE OF THE CAPACITOR BECOMES EQUAL TO THAT OF THE INDUCTOR SO NO CURRENT FLOWS. AT LOW FREQUENCY THE CAPACITIVE REACTANCE IS LOW SO ALL THE CURRENT FLOWS THROUGH THE INDUCTOR AND WHEN THE FREQUENCY IS HIGH ALL THE CURRENT WILL FLOW THROUGH THE CAPACITOR BECAUSE AT THAT POINT THE REACTANCE OF THE CAPACITOR IS LOW. SO WE OBTAIN A V-SHAPED GRAPH WITH THE PEAK OF V INDICATING THE REJECTION OF CURRENT.

Why parallel resonance circuit is called tank circuit?
traditionit is often used (like a storage tank for water is) to store resonant energy in AC circuits.
What is a circuit called that has componets in series plus componets in parallel?
Series - parallel circut
When circuit that connects several objects in one complete path is called a?
A series circuit or a parallel circuit
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....
A circuit that has only one path for the current is called?
Series, because everything in the circuit is in series.
Why is parallel resonant circuit called a rejector circuit?
because at resonance frequency in LRC parallel circuit,impedance is high, so it minimize the current. thus we say its a rejector circuit .
Why a parallel resonant circuit is called as rejecter circuit?
As a parallel resonance circuit only functions on resonant frequency, this type of circuit is also known as an Rejecter Circuit because at resonance, the impedance of the circuit is at its maximum thereby suppressing or rejecting the current whose frequency is equal to its resonant frequency.
What is the use of series and parallel resonance?
Series resonant circuits have their lowest impedance at the resonant frequency. Parallel resonant circuits have their highest impedance at the resonant frequency. This characteristic is exploited in the design of filters, oscillators and other circuits.

Why parallel resonance is termed as rejecter circuit?
THE PARALLEL rlc CIRCUIT IS CALLED A REJECTOR CIRCUIT BECAUSE IT REJECTS DOWN THE CURRENT. THE REASON IS AT RESONANCE THE IMPEDENCE OF THE CAPACITOR BECOMES EQUAL TO THAT OF THE INDUCTOR SO NO CURRENT FLOWS. AT LOW FREQUENCY THE CAPACITIVE REACTANCE IS LOW SO ALL THE CURRENT FLOWS THROUGH THE INDUCTOR AND WHEN THE FREQUENCY IS HIGH ALL THE CURRENT WILL FLOW THROUGH THE CAPACITOR BECAUSE AT THAT POINT THE REACTANCE OF THE CAPACITOR IS LOW. SO WE OBTAIN A V-SHAPED GRAPH WITH THE PEAK OF V INDICATING THE REJECTION OF CURRENT IN PARALLEL R-L-C CIRCUIT CIRCUIT,AT RESONANCE,IMPEDANCE IS MAXIMUM AND CURRENT IS MINIMUM.HENCE, SUCH A CIRCUIT WHEN USED IN RADIO STATIONS IS KNOWN AS REJECTOR CIRCUIT BECAUSE IT REJECTS OR TAKES MINIMUM CURRENT OF THAT DESIRED FREQUENCY TO WHICH IT RESONATES.(THIS RESONANCE IS OFTEN REFERRED TO AS CURRENT RESONANCE BECAUSE THE CURRENT CIRCULATING BETWEEN THE TWO BRANCHES IS MANY TIMES GREATER THAN THE LINE CURRENT TAKEN FROM THE SUPPLY.THE PHENOMENON OF PARALLEL RESONANCE IS OF GREAT PRACTICAL IMPORTANCE BECAUSE IT FORMS THE BASIS OF TUNED CIRCUITS IN ELECTRONICS.)A PARALLEL R-L-C CIRCUIT HAS THE PROPERTY OF SELECTIVITY I.E.IT CAN SELECT THE DESIRED FREQUENCY FOR AMPLIFICATION OUT OF A LARGE NUMBER OF FREQUENCIES SIMULTANEOUSLY IMPRESSED UPON IT.FOR INSTANCE IF A MIXTURE OF FREQUENCIES INCLUDING RESONANT FREQUENCY IS FED TO THE INPUT THEN MAXIMUM AMPLIFICATION OCCURS FOR THE RESONANT FREQUENCY.FOR ALL OTHER FREQUENCIES ,THE CIRCUIT OFFERS VERY LOW IMPEDANCE AND HENCE THESE ARE AMPLIFIED TO A LESSER EXTENT AND MAY BE THOUGHT AS REJECTED BY THE CIRCUIT.
What is a circuit with two or more pathways?
Generally, a circuit with multiple paths is called "parallel" because of the structure of the wiring involved. Parallel circuits have identical voltage on all paths, while current through each path is variable; whereas series circuits, having only one path, has constant current, but variable voltage.
Parallel tuned circuit in resonance frequency?
A parallel resonant circuit has at its heart an inductorand a capacitor. These are the two parallel components. They each react to voltage and current 180 degrees out of phase with each other. When we "hit" this circuit, called a parallel tank circuit, or just a tank, with voltage, one component is "putting energy into the circuit" while the other one is "storing it up" and then the two components switch roles. The result is that the tank will oscillate, and the frequency of oscillation will be determined by the value of the capacitor and the inductor.
What is a circuit with two or more branches for current to flow called?
Parallel circuit
A circuit with 4 parallel parts but only one serial part would be called a what kind of circuit?
parallel circuit
In a parallel circuit a parallel branch is uaually called a what?
It's usually referred to as one leg of the circuit.
Why inductor use in series capacitor in parallel?
That depends on the type of circuit you are talking about. Sometimes both an inductor and capacitor are both in parallel with each other. This is called a tank circuit. Sometimes they are both used in series. These are both examples of resonant circuits. Sometimes the inductor can be in parallel with an applied voltage and the capacitor in series. This is a form of high pass filter. On the other hand, the inductor can be in series and the capacitor in parallel to for a low pass filter.
A circuit with 4 parallel parts but only one serial part would be called what?
A series/parallel circuit.
