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.
A W bulb and a W bulb are connected in series in a circuit Which bulb has the greater current flowing in it?
A series circuit is where there is only one path for the current. As a result, and as a direct consequence of Kirchoff's current law, the current at every point in a series circuit is the same. The two bulbs have the same current flowing through them.
How does current flows when inductor n capacitor r in series?
The stronger the magnetic field on your inductor the greater amount of current you will have flowing through your series circuit.
How does the number of bulbs affect the amount of electrisaty in a circuit?
Adding additional lamps has no effect on the supply voltage supplied to you home. If the lamps are connected in series, then the sum of voltage-drops appearing across each lamp will equal the supply voltage. If the lamps are connected in parallel, then the voltage across each lamp will equal the supply voltage.
When is it usually desirable to connect cells in series?
In electronics circuits current is common in series circuits and voltage is common across parallel circuits. LEDs in series draw less current, but require more voltage. Total power remains the same until multiple drivers are introduced in a parallel configuration.
In which case will there be more current in each of three lamps- if they are connected to the same battery in series or in parallel?
more current will be in case of parallel because in series combination resistence is greater with respect to parallel combination
What has the greater current in the diodes bridge rectifier circuit or full-wave rectifier circuit?
They both have the same current.

Is electrical current greater before or after light bulb?
Electrical current is equal throughout a series circuit.
What happen to the current when the voltage is greater than or equal to 6 volts?
The current is greater than or equal to (6) divided by (the effective resistance of the circuit).
What happens in a circuit when the resistance gets greater?
Flow of current decreases proportionately.
What arrangement of three cells would result in the greatest electric current?
I haven't studied this for awhile, but... I assume by cell, you mean a voltage supply, like a battery. It depends on what else is in the circuit. If your circuit has a typical amount of resistance, then connecting the cells in series (as opposed to in parallel) will result in the largest voltage. Higher voltage means greater current across a resistor. However, if the resistance of the circuit is very low (like in a short circuit), then your batteries' own internal resistance may be the most significant factor, and batteries arranged in parallel may be able to sustain a higher current.

A series circuit is where there is only one path for the current. As a result, and as a direct consequence of Kirchoff's current law, the current at every point in a series circuit is the same. The two bulbs have the same current flowing through them.
What is overload current?
A current greater than which a circuit is designed to carry , may melt wires or damage elements of the circuit.This is known as overloading of current.
Why does a fuse blow?
A fuse blows when the current draw of the circuit is greater than the capacity of the fuse.
What are sreries circuits?
An arrangement circuit is a circuit where there is one and only way from the source through the greater part of the heaps and back to the source. This implies the majority of the current in the circuit must move through the greater part of the heaps. One illustration of an arrangement circuit is a string of old Christmas lights.
How does current flows when inductor n capacitor r in series?
The stronger the magnetic field on your inductor the greater amount of current you will have flowing through your series circuit.
