Resonant circuits are used in radio and television tuners to pick out broadcast signals of specific frequencies.
What is resonance of a circuit?
resonance: In an electrical circuit, the condition that exists when the inductive reactance and the capacitive reactance are of equal magnitude, causing electrical energy to oscillate between the magnetic field of the inductor and the electric field of the capacitor.
Where do we use resonant circuit and why?
At resonance, the series impedance of the two elements is at a minimum and the parallel impedance is at maximum. Resonance is used for tuning and filtering, because it occurs at a particular frequency for given values of inductance and capacitance.
What are resonant RLC circuits used for?
Resonant circuits are used to respond selectively to signals of a given frequency while discriminating against signals of different frequencies. If the response of the circuit is more narrowly peaked around the chosen frequency, we say that the circuit has higher “selectivity”.
Why is electrical resonance important?
The importance of resonance is that the circuit can either absorb or dissipate the maximum amount of energy at resonance. … The circuit then absorbs more energy from this impinging frequency than any of the other impinging frequencies.
Why is resonance a bad thing?
It may cause violent swaying motions and potentially catastrophic failure in improperly constructed structures including bridges, buildings and airplanes. This is a phenomenon known as resonance disaster. You may also read,
What are the disadvantages of resonance?
The disadvantages of resonance are as follows: A negative effect of resonance could be the effect of waves hitting a rock face. The vibration of kinetic energy from the wave resonates through the rock face causing cracks and eventually great slabs of the cliff fall into the sea. Check the answer of
What 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 the condition of 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. Read:
What happens resonant frequency?
Resonant frequency is the oscillation of a system at its natural or unforced resonance. Resonance occurs when a system is able to store and easily transfer energy between different storage modes, such as Kinetic energy or Potential energy as you would find with a simple pendulum.
What are the applications of resonant frequency?
- Oscillator circuit, radio receivers, and television sets are used for the tuning purpose.
- The series and RLC circuit mainly involves in signal processing and communication system.
- The Series resonant LC circuit is used to provide voltage magnification.
What is a series resonant circuit?
Series resonance is a resonance condition that usually occurs in series circuits, where the current becomes a maximum for a particular voltage. In series resonance, the current is maximum at resonant frequency. The series resonance current curve increases to a maximum at resonance then decreases as resonance is passed.
Where are RC circuits used?
RC Circuits: Capacitors and resistors are often found together in a circuit. Such RC circuits are common in everyday life. They are used to control the speed of a car’s windshield wipers and the timing of traffic lights; they are used in camera flashes, in heart pacemakers, and in many other electronic devices.
What is the cause of resonance?
What is Resonance? … If an object is being forced to vibrate at its natural frequency, resonance will occur. This is what causes large amplitudes of vibration when a machine’s running speed is at or near a natural frequency even if the force inputs are low.
What are some examples of resonance in 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. …
- Radio.
When should resonance be avoided?
There is an undesirable side effect of resonance. Resonance can cause a bridge, skyscrapers and towers to collapse. Even blades,piping and bearing can fail due to resonance. Therefore, resonance failures must be avoided.
