What is resonance in LC circuit?

Resonance occurs when an LC circuit is driven from an external source at an angular frequency ω₀ at which the inductive and capacitive reactances are equal in magnitude. The frequency at which this equality holds for the particular circuit is called the resonant frequency.

What is parallel resonant circuit?

Parallel resonance occurs when the supply frequency creates zero phase difference between the supply voltage and current producing a resistive circuit. In many ways a parallel resonance circuit is exactly the same as the series resonance circuit we looked at in the previous tutorial.

How do you find the impedance of a parallel LC circuit?

1. Angular Frequency ω= rad/s.
2. Capacitive reactance X_C= Ω
3. Inductive reactance X_L= Ω
4. Total LC impedance |Z_LC|= Ω

How do you find the resonant frequency of an LC circuit?

This resonant frequency is represented by the following equation:

1. f = 1 / (2π √L C)
2. f = 1 / (2π √L C) Resonant Frequency [Hz]
3. L = 1 / (4π² f² C) Inductance [H]
4. C = 1 / (4π² f² L) Capacitance [F]

What is Q factor in resonance?

The Q, or quality, factor of a resonant circuit is a measure of the “goodness” or quality of a resonant circuit. ... A practical application of “Q” is that voltage across L or C in a series resonant circuit is Q times total applied voltage.

What is the difference between RC and LC circuit?

The RC circuit is a series connection of resistance and capacitance, this circuit stores energy in the form of electric field. The RL circuit is a series combination of resistance and inductance which stores energy in the form of magnetic energy. ... Inductors are large in size and thus RL circuits are bulky and expensive.

What do you mean by resonance?

Resonance describes the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts.

What is difference between series and parallel resonance?

The main difference between series and parallel resonance is that series resonance occurs when the arrangement of the components creates the minimum impedance, whereas parallel resonance occurs when the arrangement of components creates the largest impedance.

What is meant by impedance?

In electrical engineering, electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. ... Impedance is a complex number, with the same units as resistance, for which the SI unit is the ohm (Ω).

What is meant by LC oscillations?

LC oscillations- The electric current and the charge on the capacitor in the circuit undergo electrical LC oscillations when a charged capacitor is connected to an inductor. The electrical energy stored in the capacitor is its initial charge which is named as q_m.

How do you solve an LC circuit?

lc circuit

Begin with Kirchhoff's circuit rule. Take the derivative of each term. The voltage of the battery is constant, so that derivative vanishes. The derivative of charge is current, so that gives us a second order differential equation.

What is quality factor formula?

The quality factor relates the maximum or peak energy stored in the circuit (the reactance) to the energy dissipated (the resistance) during each cycle of oscillation meaning that it is a ratio of resonant frequency to bandwidth and the higher the circuit Q, the smaller the bandwidth, Q = ƒ_r /BW.
