Resonance in Parallel RLC Circuit Explained

Описание: In this video, you will learn about the Resonance in Parallel RLC circuit.

So, in this video, you will learn the following things for the parallel Resonant circuits.

1) Resonant Condition
When the inductive reactance and parallel reactance is same in the circuit (XL=XC) then voltage and current in the circuit will be in phase. And the impedance of the circuit will be maximum and purely resistive.
So, Parallel Resonant Circuit has following characteristics:

1) The impedance of the circuit is maximum at resonance.

2) The current in the circuit will be minimum at resonance.

3) Parallel Resonant Circuit will act a Band Stop Filter, as it rejects one frequency and passes all other frequencies. And that's why it is also known as Rejector circuit.

4) The circuit will act as Current Magnifier, as the current through inductor and capacitor gets magnified Q times at resonant frequency.
