What is parallel resonance circuit

PARALLEL RESONANCE CIRCUIT

 Parallel resonance circuit

Inductor, Capacitor, and Resistor connected are parallel line its called parallel resonance circuit.

RESONANCE FREQUENCY OF PARALLEL RESONANCE CIRCUIT

F_r=1/2∏√L.C 

POWER FACTOR 

Power factor is unity of parallel resonance circuit.

IMPORTANT TOPIC OF PARALLEL RESONANCE CIRCUIT

• Parallel resonance circuit have maximum impedance. 
• Parallel resonance circuit have minimum current.
• The circuit types is capacitive after resonance frequency.
• The circuit types is inductive before of resonance frequency.
• I_C=I_L at resonance frequency.
• The circuit types is resistive at resonance frequency.
• Power factor is leading after resonance frequency.
• Power factor is unity at resonance frequency.
• Power factor is lagging before resonance frequency.
• Net total resistive current is zero.
• Voltage and current in phase.
• The amount of circuit current ot depend on the impedance.

QUALITY FACTOR IS PARALLEL RESONANCE CIRCUIT

            Q=I_C or I_L/I

NOTE

I_C>I_L = P.F lead

I_C<I_L = P.F lagging

I_L=I_C =P.F unity
