What is a resonant circuit?

The resonant circuit, also known as the LC circuit, a tank or tuned circuit, is a circuit that stores energy and repeatedly transmits it back and forth, similar to the pendulum. The energy passes between the inductor, the component of the circuit that stores energy in the magnetic field, and the capacitor that stores energy in the electric field. When both work at the same frequency, it is tuned about the perimeter. Such tuning circuits are used in tuners and amplifiers.

Inductor and capacitor cooperate. The capacitor stores energy in the form of voltage and then releases it in the form of a current. The inductor stores energy from the current in the magnetic field and then releases the energy back to the capacitor. Both components of the perimeter pass through their stored energy here and there, which is a phenomenon called oscillation. The number of times that energy is transmitted here and there is considered to be the frequency of the resonant circuit.Rcuit is like a pendulum. The person pulls the pendulum to one side to store potential energy because the pendulum is higher than thatwas before. When the pendulum is released, potential energy turns into kinetic energy, movement energy. The kinetic energy causes the pendulum to go through the neutral position to rise on the other side and store potential energy again. The pendulum oscillates back and forth until the energy occurs.

as a pendulum, the resonant circuit works most efficiently when it oscillates its preferred or resonant frequency. The speed at which each capacitor and inductor take energy and release energy is the function of time. If one tries to drive the circuit faster than its resonant frequencies, either a capacitor or an inductor will not be able to occupy and release energy quickly enough. Resonance of the circuit is defined directly 1 divided by the second root of L x C. L represents the inductance in Henries and C represents the capacity in Farads.

as a child on a swing, resonant circuits lose some energy when energyIt passes back and forth, so new energy must be added to keep the circuit running. The wires have resistance. The capacitors do not choose the as much energy they receive. The loss in the resonant circuit is measured by a quality factor or factor Q. The higher factor Q indicates that less energy is lost at each oscillation.

The

factor Q is calculated as the ratio of the amplitude or strength of oscillations based on the perimeter compared to what went to the circuit. The higher factor Q shows that less energy is needed to maintain the circuit and more output is created for each input. As an analogy, on the baby's swing, it can be compared to how far the swing moves at the pressure of the parent, compared to the extent to which the parents of the parents traveled and pushed the child.

oscillator is a special type of circuit that replaces energy lost from less than the ideal Q factor. When a child pumps a swing at the right frequency and adds energy to the system at regular intervals to overcome the loss due to friction and resistance toThose wind, the child can swing infinitely. The radio tuner is a resonant circuit with a high factor Q. Turning the knob changes the capacity of the variable capacitor. When the resonant circuit is tuned to the same frequency as the radio transmitter, the perimeter produces a high amplitude and clear sound broadcast.
