Series resonance circuit is also known as acceptor circuit why?
Because the series resonant circuit has the lowest possible impedance at resonance frequency, thus allowing the AC current to circulate through it. At resonance frequency, XC=XL and XL-XC = 0. Therefore, the only electrical characteristic left in the circuit to oppose current is the internal resistance of the two components. Hence, at resonance frequency, Z = R. Note: This effect is probably better seen with vectors. Clarification: Resonant circuits come in two flavors, series and parallel. Series resonant circuits do have an impedance equal to zero at the resonant frequency. This characteristic makes series resonant circuits especially well suited to be used as basic pass-band filters (acceptors). However, parallel circuits present their maximum impedance at the resonant frequency, which makes them ideal for tuning purposes.
Explain flywheel effect of a tank circuit?
Fly wheeling or ringing is a process where by circulating current will cause a ringing effect where that is useful is on SCR circuit to reverse power for a shot time enough to reduce holding current therefore shutting the device off
What is Microwave Gunn oscillator?
Gunn oscillators are widely used in the microwave to Terahertz region.This uses a metallic coaxial cavity (in effect, a short length of co-axial cable) to provide the resonant effect which has been modelled earlier as an LC circuit. Although it looks very different, the oscillator shares with a laser the use of a cavity. The size of this cavity determines the time/phase delay which sets the resonant frequency. In this case, each diode induced fluctuation travels up the cavity and reflected from the far end, returning to the diode after a time

vibration of one object causes another object to vibrate at natural frequencies.

What are the applications of single tuned coupled circuits?
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. For example, when we tune a radio to a particular station, the LC circuits are set at resonance for that particular carrier frequency.A series resonant circuit provides voltage magnification.A parallel resonant circuit provides current magnification.A parallel resonant circuit can be used as load impedance in output circuits of RF amplifiers. Due to high impedance, the gain of amplifier is maximum at resonant frequency.Both parallel and series resonant circuits are used in induction heating.LC circuits behave as electronic resonators, which are a key component in many applications:AmplifiersOscillatorsFiltersTuners
What is meant by resonant?
The term "resonant" means echoing or resounding. It also means strong and deep in tone. Resonance is also defined as having a lasting presence or effect.
Why is sharpness of resonance inversely proportional to the damping force?
The sharpness of resonance is inversely proportional to the damping force because damping reduces the amplitude of oscillations in a system, leading to a broader resonance peak. Higher damping forces cause energy to be dissipated more quickly from the system, resulting in a less pronounced peak at the resonant frequency.
Why does resonance make sound louder?
Resonance enhances sound by amplifying specific frequencies that correspond with the natural frequency of a system. When an external sound wave matches the resonant frequency of an object, it causes the object to vibrate more vigorously, resulting in a louder sound. This amplification effect is what makes resonance contribute to making sound louder.
What is the effect of frequency on amplitude?
The relationship between frequency and amplitude depends on the system being analyzed. In some systems, increasing frequency may result in an increase in amplitude (resonance), while in others it may decrease. Generally, higher frequencies can lead to higher amplitudes in resonant systems, while non-resonant systems may have a more complex relationship between frequency and amplitude.
Does resonance has no effect on the loudness of an instrument?
False

Explain about the effect of the time constant RC in envelope detector?
The circuit that generates signal having the shape like imaginary curve is called an envelope detector. The effect of the time constant RC in envelope detector is that the output follows the input curve and the circuit performs like a demodulator.
How the mesomeric effect occurs?
The mesomeric effect, also known as resonance effect, occurs when electrons are delocalized across a molecule due to the presence of multiple resonance structures. This results in stabilization of the molecule's electronic structure and can influence its reactivity and stability. The mesomeric effect is commonly observed in conjugated systems such as aromatic compounds.
What are the differences between resonance effect and inductive effect?
One difference is that inductive effects are based on the electronegativity of an atom and occur through the sigma bond network. The resonance effect donates electrons to the benzene ring and occurs through the pi bond network.
What is resonance effect and inductive effect?
Resonance effect: It is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis formula.A molecule or ion with such delocalized electrons is represented by several contributing structures called as resonance structures or canonical forms. Inductive Effect: It is a permanent effect. When group attached to carbon atom attract electrons from them or push the electrons toward it is called as Inductive effect.
