# Difference Between Series and Parallel Resonance Circuits

In this article we will discuss about the difference between series and parallel resonance circuits. We will also know that what is working application of series and parallel resonance circuit.

## Difference Between Series and Parallel Resonance Circuits

Now we are going to learn about basic difference between series and parallel resonance circuits.

Series Resonance Circuits |
Parallel Resonance Circuits |

1. Series Resonance circuit is an acceptor circuit. | Parallel Resonance circuit is an rejecter circuit |

2. At resonant the impedance is a maximum equal to the resistance in circuit. | At resonance the impedance is maximum nearly equal to infinity. |

3. In resonance Current at resonance is maximum = V/R | In Parallel circuit current at resonance is minimum = V/(L/CR) |

4. In Series circuit power factor is unity | In parallel power circuit power factor is unity |

5. Series circuit magnifies voltage | Parallel resonance circuit magnifies current |

6. Series resonance magnification in WL/R | Parallel resonance circuit magnification is WL/R |

7. In series resonance effective impedance is R which is R= V/ Resonant current | In parallel resistance effective resistance is L/CR
It is basic difference between series and parallel resonance circuits |

8. Series Resonance used in the turning circuit to separate the wanted frequency from the incoming frequency by offering low impedance of that frequency | Parallel Resonance used to present a maximum impedance to wanted frequency usually in the plate circuit of values. |

### Parallel Resonance Frequency

A parallel resonance circuit is consists of and inductive coil of inductance L and resistance R. A capacitor is connected in parallel to this coil. such a circuit is said to be in electrical resonance when the reactive component of line current becomes zero. The frequency at which this happen is called as resonance frequecy. It is also describe above title which is difference between series and parallel resonance circuits.

#### Features of parallel resonance circuits

- Impedance at resonance is maximum
- Current at resonance is minimum,
- Effective Impedance is L/CR
- Parallel resonance power factor is unity
- It magnifies current

Hence these are Difference between series and parallel resonance circuit. If you will find any incorrect in above article you must comment below in comment box.
