How to understand the bypass function of capacitance in power supply circuit

We know that capacitors are often used in power circuits to achieve bypass, de-coupling, filtering and energy storage, so how do we understand these functions? Today, Xiaobian first to give you an analysis of the bypass. This IS A CAPACITOR THAT CAN BYPASS THE high-frequency component of ALTERNATING current mixed with high-frequency and LOW-frequency currents, …

Semiconductor triode

Semiconductor triode 1. Structure and type (1) Structure Triode is composed of two PN junctions (collecting junction, emitting junction), three regions (collecting region, base region, emitting region), and three electrodes (collector, base and emitter). (2) Type It can be divided into NPN type and PNP type. The direction of the emitter arrow indicates the direction …
