uzair_ha91 said:"At resonance frequency, the circuit impedance is maximum. It is resistive and its value is given L/Cr..."
The book doesn't explain how impedance equals L/Cr, so I'm confused here. How is it derived? (Can you please show all the steps?)
Thanking in advance...
A parallel resonance LC circuit is a type of electrical circuit that consists of a capacitor and an inductor connected in parallel. It is also known as a tank circuit because it can store and release energy like a tank.
In a parallel resonance LC circuit, the capacitor and inductor work together to create a resonant frequency. At this frequency, the circuit becomes highly reactive, causing the voltage across the capacitor and current through the inductor to reach their maximum values. This results in a high amount of energy being stored in the circuit.
The resonant frequency of a parallel resonance LC circuit is determined by the values of the capacitor and inductor. It can be calculated using the formula: f = 1/(2π√(LC)), where f is the resonant frequency in Hertz, L is the inductance in Henrys, and C is the capacitance in Farads.
Parallel resonance LC circuits have various applications in electronic devices, such as in radio tuners, filters, and oscillators. They are also used in power systems for power factor correction and in wireless charging systems.
The resonant frequency of a parallel resonance LC circuit is directly affected by the values of the capacitor and inductor. Increasing the capacitance will decrease the resonant frequency, while increasing the inductance will increase the resonant frequency. Changing these values can also affect the amount of energy stored in the circuit and the frequency response of the circuit.
