What is the role of inductance Many people do not know the main three functions of inductance, the following small series to specific. 1, block traffic straight For dc, inductance is equivalent to a short circuit, while for AC, inductance is a hindrance, the higher the ac frequency, the greater the inductance hindrance. 2. Transformer …

Working principle of semiconductor refrigeration sheet In principle, the semiconductor chip is a heat transfer tool. When an electric current flows through a thermocouple formed by an N-type semiconductor material and a P-type semiconductor material, heat transfer occurs between the two ends. Heat is transferred from one end to the other, resulting in a temperature …
1. Factors affecting resistivity Resistivity is a physical quantity used to express the electrical resistance of various substances. The ratio of the product of the resistance and cross-sectional area of the component made of a substance (20°C at room temperature) to its length is called the resistivity of the substance. The unit of electrical resistivity …

I. Reading method of ceramic capacitor 1. Method of representation of capacitor capacity The basic unit of capacitor capacity is "farad" (F), 1/1000000 (millionth) of 1 farad is 1 micromethod (μF), 1/1000000 of 1 micromethod is 1 PF (1 picomethod or 1 picomethod). The relationship between them is a million (or 10 to the sixth) …
