Inductor And Capacitor In Parallel Resonance

October 20, 2019

The voltage across the capacitor falls to zero as the charge is used up by the current flow. Let us understand the parallel resonance with the help of a circuit diagram shown below.

Lc Circuit Wikipedia

If an inductor is connected across a charged capacitor the voltage across the capacitor will drive a current through the inductor building up a magnetic field around it.

Inductor and capacitor in parallel resonance. The results are shown in the figure below. The capacitor is a device consisting of just two parallel plates which is capable of storing energy in electric field and an inductor is a coil wounded over a magnetic material which is also capable of storing energy in magnetic field. As told earlier a typical tank circuit just consists of an inductor and capacitor connected in parallel.

Parallel resonant circuit is a generic term which consists of resistor inductor as well as a capacitor in parallel connection. In the following series circuit examples a 1 w resistor r1 is placed in series with the inductor and capacitor to limit total current at resonance. A parallel circuit containing a resistance r an inductance l and a capacitance c will produce a parallel resonance circuit when the resultant current through the parallel combination is in phase with the supply voltage.

An rlc circuit or lcr circuit is an electrical circuit consisting of a resistor an inductor and a capacitor connected in series or in parallel. Parallel resonance parallel resonance means when the circuit current is in phase with the applied voltage of an ac circuit containing an inductor and a capacitor connected together in parallel. The total impedance of a parallel lc circuit approaches infinity as the power supply frequency approaches resonance.

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. For a tank circuit with no resistance r resonant frequency can be calculated with the following formula. Resonance occurs when capacitive and inductive reactances are equal to each other.

The rlc part of the name is due to those letters being the usual electrical symbols for resistance inductance and capacitance respectively. A parallel circuit containing a resistance r an inductance l and a capacitance c will produce a parallel resonance also called anti resonance circuit when the resultant current through the parallel combination is in phase with the supply voltage. The extra resistance inserted to influence resonant frequency effects is the 100 w resistor r2.
