What is series resonance circuit

   RESONANCE CIRCUIT

 CONDITION OF RESONANCE
  • Must be have two components which is storage energy form of magnetic field and electric field.
  • Inductor is energy storage device which is energy store form of magnetic field.
  • Capacitor is a energy storage device which is energy store form of electric field.
  • Resistive circuit is source voltage and  source current same phase.
  • Power factor must be unity.

  • XL=XC

RESONANCE FREQUENCY 

       Fr=1/2∏√L.C

            
TYPES OF RESONANCE CIRCUIT

            1)Series resonance circuit.
            2)Parallel resonance circuit.

SERIES RESONANCE CIRCUIT
Series resonance circuit
            Inductor, Capacitor, and  Resistor are connected series line, its called series resonance circuit.

IMPORTANT TOPIC OF SERIES RESONANCE CIRCUIT
  • Series resonance circuit have minimum impedance.
  • Series resonance circuit have maximum current.

  • VL=VC  at resonance frequency.

  • XL=XC at resonance frequency.

  • In the circuit is maximum current.

  • In the circuit is minimum impedance.

  • The circuit types is capacitive before of resonance frequency.

  • The circuit types is inductive after resonance frequency.

  • At the resonance frequency the circuit types is resistive.

  • Voltage and current in phase.          
OTHER NAME OF SERIES RESONANCE CIRCUIT

            1)Acceptor circuit.
            2)Series tuned circuit.

APPLICATION OF SERIES RESONANCE CIRCUIT

            1)As a band pass filter.
            2)Frequency selector circuit in radio an T.V receivers.  

POWER FACTOR OF SERIES RESONANCE CIRCUIT

power factor is unity of series resonance circuit.

What are the types of filter circuits

FILTER CIRCUIT FILTER               Filter is an electronic circuit. Filter circuit is very useful electronic device which can filter pulse of frequency. Filter circuit can stop or pass particular band of frequency. TYPES OF FILTER CIRCUIT               1)Low pass filter circuit.               2)High pass filter circuit.               3)Band pass filter circuit.               4)Band stop filter circuit. 1)LOW PASS FILTER CIRCUIT Low pass filter circuit                                                       This filter circuit allow only low frequency and which reject above the all cut-off frequencies its called low pass filter.

What is meant by DC current

The term direct current (DC) supply is given to a supply source that makes current to flow  through a circuit in one direction only.        Batteries and some types of generators give DC supply of constant voltage.    ## DC supply is not distributed by electric supply agencies in India.      A dvantage of DC supply         1) D.C is better for electric arc-welding.      2) D.C is essential for electroplating.      3) D.C is essential for the operation of various electronic equipment .
