Because they can be used to obtain or get an output (on a series connected resistance with them) for a specific frequency of the input signal. This is the ideal case, but in fact, the resonance circuit passes a band (not a single frequency) of input signals' frequencies to take them at the output terminal. They are also termed as ( filters or filtering circuits ). They are called selective as they function as if they select signals of specific frequencies to be passed to the output.

What are stationary part of dc motor?
The stationary part of any motor or generator is termed the 'stator', and the rotating part is termed the 'rotor'.The stator comprises the main frame (chassis), the magnetic circuit, and field windings.
What is difference between ac series motor and dc series motor?
AC series motor uses the electric current to run the motor. Whereas DC motor uses the battery power to run it.AnswerAn a.c. series motor is termed a 'universal motor', because it will run on either a.c. or d.c. A.C. series motors are constructed in essentially the same way.
What is coherent machine?
Machines which swing together are termed as coherent machine.
Why do you represent leakage flux in a transformer by inductive reactance?
A transformer is often represented by an equivalent circuit, in which the transformer itself is considered to be 'ideal', and its basic losses are then represented as resistance and reactance in series with both the primary and secondary windings for a loaded transformer, or just on the primary side for a transformer on open circuit.The transformer's primary flux comprises two components: the main flux, which links the primary and secondary windings, and a leakage flux which links just the primary winding. The leakage flux is considered arising from a self inductance in series with an 'ideal' primary winding. The reactance of this inductance is termed the primary leakage reactance. The voltage drop across this reactance will lead the primary no-load current by 90 degrees which, when added to the voltage drop across the resistance of the primary winding, acts to reduce the back emf of the primary winding below the value of the applied voltage and cause it to lag.A similar explanation accounts for the an inductance and resistance in series with the secondary winding, when the transformer is loaded.
What is working principle of inductor?
A changing current through an inductor induces a voltage into the inductor, the direction of which always opposes the change in that current.So, in a d.c. circuit, an inductor will oppose (not prevent) any rise or fall in current, although the magnitude of that current will be determined by the resistance of that inductor, not by its inductance.In an a.c. circuit, because the current is continuously changing both in magnitude and in direction, it acts to continuously oppose the current due to its inductive reactance. Inductive reactance is proportional to the inductance of the inductor and the frequency of the supply. The vector sum of the inductive reactance of the inductor and the resistance of the inductor, is termed the impedance of the inductor. Inductive reactance, resistance, and impedance are each measured in ohms.
What is a catheter inserted into an artery and manipulated to a further order is termed?
Selective catheter placement
What do you call the path electricity takes?
The electrical path is termed an electrical circuit.
What happens when a curcuit is closed?
To close a circuit in electrical terminology is to close any open devices that are in series with a connected load. Once this happens the current will flow through the load and the load is then termed as energised. In the case of a motor circuit the motor will operate. In the case of a lighting circuit the lamps in the circuit will energise and light the area in which they are installed.
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 systemic circuit?
In the systemic circuit, oxygenated blood is distributed to body tissues.The systemic circuit also distributes nutrients to the body tissues and removes waste.
When sedimentary particles move in series of short bounces the process is termed?
Saltation.
How do single circulatory system work?
when the blood follows one circuit pathway through the body , it is termed as single circuit plan
Does resonance occur in the middle ear?
Resonance does occur in the middle ear. The middle ear is responsible for amplifying sound waves before they are transmitted to the inner ear. This amplification is achieved through the vibrations of the ear ossicles and the resonance of the tympanic membrane and middle ear cavity.
What are stationary part of dc motor?
The stationary part of any motor or generator is termed the 'stator', and the rotating part is termed the 'rotor'.The stator comprises the main frame (chassis), the magnetic circuit, and field windings.
What year was the TV Series Christy released?
Christy is a TV series with 20 episodes that was aired in CBS. It was based on a novel and was released in April 1994. It may be termed as a Family drama series.
How do antidepressants prescribed to treat premenstrual syndrome work?
The most effective of these include sertraline (Zoloft), fluoxetine (Prozac), and paroxetine (Paxil).
A device that protects a circuit from current overload is called?
Fuses or circuit breakers are termed 'overcurrent protection devices', which protect circuits from either an overload current or a short-circuit current.
