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. Let us understand the Parallel Resonance with the help of a circuit diagram shown below.
parallel-resonance-circuit-diagramConsider an Inductor of L Henry having some resistance of R ohms connected in parallel with a capacitor of capacitance C farads. A supply voltage of V volts is connected across these elements. The circuit current Ir will only be in phase with the supply voltage when the following condition given below in the equation is satisfied.
Explanation:
Therefore, it makes no difference if the inductor or capacitor are connected in parallel or series. ... Thus at resonance, the impedance of the parallel circuit is at its maximum value and equal to the resistance of the circuit creating a circuit condition of high resistance and low current.
