Question

When conducting an experiment using a Wein bridge oscillator, the experimenter initially did not get a sinusoidal waveform, but later obtained one. What might be the reason for not getting the sinusoidal waveform initially?

Answer 1

The initial lack of a sinusoidal waveform in an experiment using a Wein bridge oscillator could be due to the lack of resonance.

Step-by-step explanation:

Due to a lack of resonance, the experimenter initially failed to obtain a sinusoidal waveform when using a Wein bridge oscillator. The output frequency of the Wein bridge oscillator circuit is intended to coincide with the oscillator's resonant frequency. The input signal's frequency must be changed to coincide with the oscillator circuit's resonant frequency in order to produce a sinusoidal waveform. A sinusoidal waveform is produced and resonance occurs when the frequency is properly adjusted.
