Basic Knowledge of Electronic Components (2)Capacitors are one of the most widely used electronic components in electronic equipment, widely used in straight separation, coupling, bypass, filtering, tuning loop, energy conversion, control circuit and so on.
The essence of a capacitor is the storage of electric field energy, and any electrostatic field is composed of a capacitor. Isolated conductors and capacitors formed at infinity are the basis, while grounding is equivalent to connecting with the earth to form a whole. The diode, the unidirectional conductive element, is the soul of the electronic circuit.
Understanding the characteristics of each component is key, let's start with the basics: the decoding of the resistor/resistor, as the basic element in the circuit, identified with an "r", such as r13. The functions of resistance include shunt, current limiting and so on. Note when identifying the unit ohm (Ω), such as 472, which means 7Kiloohms (kΩ).
