an oscillator is associated with an basic amplifier for
producing oscillations,for production of oscillations the
amplifier needs some input voltage but under the oscillation
condition the input voltage is zero,why?

Answer Posted / vinit panchal
it is happen by the random electrons which is present in the amplifier. random electrons present in resistor .this random electrons will produce small amount of current in amplifier.this small current is amplify by the amplifier. And in this amplifier has a positive feedback so o/p of amplifier will amplify until the oscillation start. phase shift of input and output will be same in oscillation.
