Oops. Completely forgot about that. w is angular frequency but the question said units should be in Khz which is linear frequency. I just divided 14.14/2pi and I got the right answer of 2.25. thanksgneill said:
A parallel resonant circuit frequency is the frequency at which a parallel resonant circuit, composed of a capacitor and inductor, has the highest impedance and therefore experiences a resonance effect.
The parallel resonant circuit frequency can be calculated using the formula: fr = 1 / (2π√(LC)), where fr is the resonant frequency, L is the inductance in henries, and C is the capacitance in farads.
The parallel resonant circuit frequency is significant because it is the frequency at which the circuit has the highest impedance. This means that at the resonant frequency, the circuit is most efficient at storing and transferring energy between the capacitor and inductor.
The parallel resonant circuit frequency can have a significant impact on the overall performance of a circuit. It can determine the bandwidth of the circuit, influence its resonance stability, and affect its ability to filter out unwanted frequencies.
The parallel resonant circuit frequency can be adjusted by changing the values of the inductance and capacitance components. By increasing or decreasing these values, the resonant frequency can be shifted to a desired frequency. Additionally, the frequency can also be adjusted by changing the voltage or current in the circuit.
