Answer 1

Explanation:

Hear this out loud

Resistor-capacitor (RC) relaxation oscillators are generally produced using operational voltage amplifiers or integrated circuits equipped with timers. When power is applied, the amplifier causes a capacitor to begin charging toward the voltage threshold under a preset time constant.
