Resonant Tank Circuit
Resonant tank circuit
An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together.
What is the resonant frequency of the tank circuit?
Explanation: The parallel resonant circuit is generally called a tank circuit because of the fact that the circuit stores energy in the magnetic field of the coil and in the electric field of the capacitor. The resonant frequency fr = (1/2π) √((1/LC)-(R2/L2)).
How does a resonant circuit work?
A resonant circuit is formed when a capacitor and inductor (coil) are in parallel or in series. The two circuit elements will block or pass a single specific frequency out of a divers mix. For this reason, resonant circuits make possible radio and TV transmission and reception and perform many other useful tasks.
What is RLC tank circuit?
An RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. The name of the circuit is derived from the letters that are used to denote the constituent components of this circuit, where the sequence of the components may vary from RLC.
Why is it called a resonant circuit?
As a series resonance circuit only functions on resonant frequency, this type of circuit is known as an Acceptor Circuit because at resonance, the impedance of the circuit is at its minimum so easily accepts the current whose frequency is equal to its resonant frequency.
Why are resonant circuits important?
Resonant circuits exhibit ringing and can generate higher voltages or currents than are fed into them. They are widely used in wireless (radio) transmission for both transmission and reception.
Which are the two types of resonant circuit?
The resonant circuit can be a simple series or parallel LC circuit, or a circuit formed by an inductor and two capacitors (parallel LCC) or two inductors and one capacitor (parallel LLC), or a parallel LLCC circuit (Fig. 12a).
What is meant by resonant frequency?
Resonant frequency is the natural frequency where a medium vibrates at the highest amplitude. Resonant frequency is usually denoted as f0. Resonance is witnessed in objects in equilibrium with acting forces and could keep vibrating for a long time under perfect conditions.
What is resonant frequency formula?
The resonant frequency is defined as the frequency of a circuit when the values of capacitive impedance and the inductive impedance become equal. It is defined as the frequency at which a body or system reaches its highest degree of oscillation.
What are the 3 conditions for resonance?
The conditions to produce resonance in an object are: The object must have a minimum of one natural frequency of vibration. The object must be driven by an external force of vibration. The frequency of the external vibrating force must be similar to the object's natural frequency of vibration.

Why do we use RLC circuit?
RLC circuits have countless applications outside of being filters. For example, RLC circuits are used for voltage magnification and parallel RLC circuits can be used for current magnification. Another use for RLC circuits is in induction heating.
Is RLC circuit AC or DC?
RLC circuit is an electric circuit made of a resistor, inductor, and capacitor which are connected in series with an alternating current AC power supply.
What is LCR and RLC circuit?
An LCR circuit, also known as a resonant circuit, tuned circuit, or an RLC circuit, is an electrical circuit consisting of an inductor (L), capacitor (C) and resistor (R) connected in series or parallel. The LCR circuit analysis can be understood better in terms of phasors.
What is a tank circuit used for?
Applications of Tank Circuit These circuits are used for tuning transmitters & receivers of radio. Once these circuits get charge then generate a precise frequency. For example, once you turn on a radio toward a particular station, the charge can be changed on a circuit then it vibrates at that frequency.
Why is resonance bad in a circuit?
Electrical resonance amplifies the magnitude of voltage or current, or both. The increase in amplitude, whether mechanical or electrical, places more stress on motor and pump components, negatively affects operation (e.g., increased vibration, instability and energy consumption) and leads to premature failure.
What is difference between resonant and resonance?
"Resonant" is an adjective, and is used properly in sentence B. "Resonant" and "resonance" are frequently confused, usually as in the example A above. Also, "resonate" is a verb; "resonator" is a noun (that which has a "resonance").
What are the applications of resonant circuits?
Resonant circuits (series or parallel) are used in many applications such as selecting the desired stations in radio and TV receivers. A series resonant circuit is used as voltage amplifier. A parallel resonant circuit is used as current amplifier. A resonant circuit is also used as a filter.
How is resonance used in real life?
A playground swing is one of the familiar examples of resonance. When we push the swing, it starts moving forward and backwards. If a series of regular pushes are given to the swing, its motion can be built. The person who is pushing the string has to match the timing of the swing.
What are four examples of resonance?
Mechanical Resonance
- musical instruments (acoustic resonance).
- Most clocks keep time by mechanical resonance in a balance wheel, pendulum, or quartz crystal.
- Tidal resonance of the Bay of Fundy.
- Orbital resonance as in some moons of the solar system's gas giants.
- The resonance of the basilar membrane in the ear.
