Learn the difference between ideal and practical parallel RLC resonant circuits and how to calculate admittance and impedance in parallel RLC resonant circuits. A parallel RLC circuit contains a resistor (R), an inductor (L), and a capacitor (C) connected in parallel.
The series resonant circuit has a minimum impedance at the resonance frequency. So, the impedances of series and parallel LC circuits at resonance are opposites. As a consequence of the peak in the impedance value of a parallel resonant circuit, there is a dip in the current taken from the supply at the resonance frequency.
A parallel resonant circuit has a 90°phase angle at supply frequencies well below resonance. This changes to zero as the resonance frequency is approached and then approaches 90° at frequencies well above resonance. Image used courtesy of Amna Ahmad Example 1
Figure 8.3.5: Impedance plot for parallel resonant circuit. If the parallel resonant circuit is driven by a current source, then the voltage produced across the resonant circuit (sometimes referred to as a tank circuit) will echo the shape of the impedance magnitude.
A parallel RLC circuit is a circuit containing a resistance (R), an inductance (L), and a capacitance (C) in parallel. When the resultant current through this parallel combination is in phase with the supply voltage, it produces a parallel resonance (or anti-resonance) effect.
A parallel resonant circuit stores the circuit energy in the magnetic field of the inductor and the electric field of the capacitor. At resonance, there will be a large circulating current between the inductor and the capacitor due to the energy of the oscillations, then parallel circuits produce current resonance.
