2, dielectric basic amplifier circuit is a transistor amplifier circuit, randomly check the Internet to understand
3, OCT, OCL for the complementary symmetrical power amplifier circuit to be able to The OCT and OCL are complementary symmetrical power amplifier circuits that can reduce output resistance and improve load carrying capability, and the two circuits are different
4. Capacitors can be divided into polarized and non-polarized capacitors, with the former labeled positive and negative, and the latter having no polarity
5. Resistors can be categorized in different ways, such as carbon film resistors, cement resistors, metal film resistors, and wirewound resistors, etc., and in terms of power, they can be categorized in terms of 0.25W, 0.5W, 1W, and 2W. The resistors are rated at 0.25W, 0.5W, 1W, 2W, etc. According to the accuracy of the resistance value, there are common resistors with an accuracy of ± 5%, ± 10%, ± 20%, etc., and precision resistors with an accuracy of ± 0.1%, ± 0.2%, ± 0.5%, etc. The resistors are available in a wide range of colors and sizes.
The above is a general answer, the specific details of the relevant content to be respectively check the relevant information
