Parallel Resonance Frequency. At this resonant frequency the crystal appears completely resistive in the circuit. The resonant frequency of a parallel circuit is the frequency at which the sum of the two reactive components becomes equal to zero.
At this resonant frequency the crystal appears completely resistive in the circuit. Ir v zr where zr is circuit impedance at parallel resonance. Resonant radian frequency for parallal rlc circuit.
Let s discuss the series resonance mode.
In parallel rlc circuit resonance occurs when the imaginary term of admittance y is zero. At parallel resonance the circuit current is minimum and is given by. On the other hand the resonant frequency in parallel resonance circuit is given as 1 2 π 1 lc r 2 l 2 0 5. 1 x c 1 x l.
