First of all, we connect a 9V power supply to the circuit. Secondly, a resistor R1 passes an electrical current to biased the Microphone (MIC1). The R1 is a current limiting resistor for MIC1. It is ready to work. When we make a sound to MIC1, it causes the electrical signals to change. Then, the sound signal flows through a coupling capacitor-C1.
