Resistance is an ordinary component, but there is an unusual way, in doing electronic design for nearly ten years today, I this small electrician just realized some way, here to share with you. There are many parameters of resistance, usually we generally pay attention to value, accuracy, amount of power, …
Aluminum Capacitors are an extremely popular choice in the electronics industry due to their stable performance, low cost, and wide selection. However, do you know everything about them? What are Aluminum Capacitors? Aluminum capacitors are a type of capacitor used in electronics. They are made of aluminum and can be …
Electronic components are the general term for components and devices. It is a component of electronic components and small machines and instruments. It is often composed of several parts and can be used in similar products. Often refers to electrical appliances, radio, instrumentation and other industrial parts, such as capacitance, …
Valve radio Vacuum tube radio, is a product of the last century, along with the radio started immediately become the era of “to be bestowed favor on newly” due to the emergence of science and technology constantly development of the transistor, the 60 s and seventy s last century tube …
Integrated circuit board Integrated circuit board is a carrier of integrated circuit. But when you talk about integrated circuit boards, you also bring integrated circuits with you. Integrated circuit board is mainly composed of silica gel, so generally green. Integrated circuit board (IC) is made of semiconductor technology, many transistors, …
What is the wiring method of potentiometer For general potentiometer, near the center is a vane, center head is inside a resistance wire, with two pins on both ends of the resistance wire connected directly, the two pins are connected the input signal and ground (some don’t pick up), even …
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 …
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 …
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. …
A brief introduction of color ring resistance identification method Color ring resistance identification method refers to the resistance above the use of four color rings or five color rings or six color rings to represent the resistance value. The color information representing the resistance value can be read from any …
