A Wien bridge oscillator generates a sinusoidal waveform. The oscillation frequency can be determined by the components of the circuit, typically in the audio frequency range. The circuit is designed to provide sustained oscillations at the desired frequency.
In an RC phase shift oscillator, one emitter follower stage is typically used to provide the required phase shift. In a Wien bridge oscillator, two emitter followers are used to achieve the required feedback and oscillation.
A Wien-bridge oscillator generates a sinusoidal waveform using an op-amp and a feedback network with both resistors and capacitors, while a phase-shift oscillator uses an RC network to introduce phase shifts in the feedback path to generate oscillations. Wien-bridge oscillators are typically used for audio frequency applications, whereas phase-shift oscillators are commonly used for higher frequency applications.
The expectation value of potential energy for a harmonic oscillator is equal to half of the oscillator's spring constant multiplied by the square of the oscillator's displacement from its equilibrium position.
The Clapp oscillator is a variation of the Colpitts oscillator that includes an additional capacitor in series with the inductor to improve frequency stability. This additional capacitor in the Clapp oscillator helps reduce the effect of the active device's parasitic capacitance, leading to better frequency stability compared to the Colpitts oscillator.
A Wein Bridge Oscillator is a oscillator which is used for the measurement of Audio Frequency.

They are used in electronics.
The simplest application of a UJT is as a relaxation oscillator, which is defined as one in which a capacitor is charged gradually and then discharged rapidly.
In an RC phase shift oscillator, one emitter follower stage is typically used to provide the required phase shift. In a Wien bridge oscillator, two emitter followers are used to achieve the required feedback and oscillation.
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network
