## Can resonance occur in LC circuit?

The resonance effect of the LC circuit has many important applications in signal processing and communications systems. The most common application of tank circuits is tuning radio transmitters and receivers.

### What is LC oscillation explain it?

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 [latex]q_m[/latex]

#### What is the use of LC oscillation?

The LC circuit is used to select or generate a specific frequency signal. The application of LC circuits is reflected in many electronic devices, especially radio devices, such as transmitters, radio receivers and television receivers, amplifiers, oscillators, filters, tuners and frequency mixers.

What is the resonant frequency of LC circuit?

10 kHz
Resonant frequency of a LC circuit is 10 kHz.

What are the examples of resonance?

Let’s see the examples of resonance that occur in our everyday life.

• Swing. A playground swing is one of the familiar examples of resonance.
• Guitar. A guitar produces sound entirely by vibration.
• Pendulum.
• Singer Breaking A Wine Glass.
• Bridge.
• Music system playing on the high heavy beat.
• Singing in shower.

## Why do LC circuits resonate?

LC circuits Resonance of a circuit involving capacitors and inductors occurs because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor, and then the discharging capacitor provides an electric current that builds the magnetic field in the inductor.

### What is LC oscillator explain with diagram?

Oscillators work because they overcome the losses of their feedback resonator circuit either in the form of a capacitor, inductor or both in the same circuit by applying DC energy at the required frequency into this resonator circuit. …

#### Why LC oscillations are not realistic?

Answer: L-C oscillations are not realistics because and element whether its an inductor or capacitor have some lossy element i.e. resistance. An inductor is made of coil and coil have some resistance same capacitor is also have some resistance. So practically L-C oscillations will not occur for intinite time.

What are the applications of LC?

The applications of LC oscillators mainly include in radio, television, high-frequency heating, and RF generators, etc. This oscillator uses a tank circuit which includes a capacitor ‘C’ and an inductor ‘L’.

What is the use of LC filter?

Low-pass Filters(LPF) Low-pass filters are filter circuits that pass DC and low-frequency signals and cut high-frequency signals. They are the most widely used filter circuits and are mainly used to cut high-frequency noise. In audio, they are also used to cut treble/mid-range sound components of bass speakers.

## How do you calculate LC resonance?

Resonance in the LC circuit appears when the inductive reactance of the inductor becomes equal to the capacitive reactance of the capacitor. So: xL= 2 * π * f * L. xC= 1 / (2 * π * f * C)

### What is a simple definition of resonance?

1a : the quality or state of being resonant. b(1) : a vibration of large amplitude in a mechanical or electrical system caused by a relatively small periodic stimulus of the same or nearly the same period as the natural vibration period of the system.

#### What is the resonant frequency of a LC oscillator?

The resonant frequency of the LC oscillator is f 2 = 1/ ((2π √ (LC)) 2 L = 1/ (4π 2 f 2 C) L = 1/ (4π 2 (22.7 × 106) 2 × 47 × 10 -12)

When do you connect an inductor to a LC oscillator?

The combination of an inductor and a capacitor creates an LC oscillator circuit. Let us learn more. Whenever we connect a charged capacitor to an inductor the electric current and charge on the capacitor in the circuit undergoes LC Oscillations.

What are the different types of LC oscillators?

In this oscillator, amplifier and LC filter network can be constructed in several ways. Thus, these oscillators are come in different forms such as Hartley oscillators, Armstrong oscillator, Colpitts oscillators, Clapp oscillators, etc.

## What is the topology of a LC oscillator?

LC oscillator topology By looking at figure 1, you’ll see that the feedback factor (the voltage gain of the feedback network), B (f), can be stated in a form that resembles the equation describing a resistive voltage divider. Commonly Z1 and Z2 are the same type of reactance, and Z3 is of the “opposite” type.
