Wheels, endlessly repeating the same motion, provide power, movement, or timing for machines.Oscillators do the same in electronics, producing continually repeated pattern voltage or current that can move an electron beam, supply pulses to control a computer, or generate waves that carry signals through cables or space.An oscillator can be made connecting the output of an amplifier to its own input through something that delays the signal.If the delay is arranged so at just one frequency the rising and falling voltages at the input and output of the amplifier stay in step, they will reinforce.One little power is needed to keep this pattern going.The amplifier can deliver the rest to do useful work in other circuits.
