Components on the circuit board

What common components are included in the circuit? After understanding the basics of the circuit, we also need to know the common components on the circuit, and master the role of each component in the circuit. Capacitor, its function is filtering, energy storage, etc.; Resistance, its function is current or voltage division; MOS tube, its function is voltage conversion or step-down. Each component has a different function, and some faults can be quickly diagnosed through these components.
