The RC network samples the amplifier output and feeds a delayed version back to the input. Any random noise at the input reappears at the input, amplified and delayed. The delay time determines the frequency of oscillation, not resonance of a tuned circuit.

In RC oscillator th amplifier will produce slightly shift of 180degree and each and each and every RC community will produce slightly shift of 60degree so there are 3 RC networks so the entire hase shift will be 180degree . The amplifier & RC community completely roduce 360degree section shift which satisfies Barkhausean criterian.

Oscillations are maintained by a positive feedback loop. This feeds back to the input a small phased signal that continuously gives the oscillator a kick in the butt to continue its oscillations.
