1. Capacitance are generally represented by "C" plus a number in the circuit (for example, C13 represents the capacitor numbered 13). A capacitor is a component composed of two metal films close together and separated by an insulating material. The characteristic of the capacitor is mainly to block DC and pass AC. The size of the capacitor [...]
Axel Van Rozenberg, Executive Vice President of Operations of the World Bank, said on the 9th that the World Bank intends to raise US$2 billion by the end of April to help approximately 40 developing countries and regions obtain the new crown vaccine. During the 2021 IMF and World Bank spring meeting on the new crown [...]
The main technical indicators of capacitors are capacitance, withstand voltage and temperature. In addition to these three main indicators, the more important of other indicators is equivalent series resistance (ESR). Some capacitors have a golden strip line with a big hollow letter "I" printed on it, which indicates that the capacitor is a LOW ESR low-loss [...]
The role of electrolytic capacitors In the power supply circuit, the rectifier circuit turns AC into pulsating DC, and a larger capacity electrolytic capacitor is connected after the rectifier circuit. Using its charge and discharge characteristics, the rectified pulsating DC voltage becomes a relatively stable DC Voltage. In practice, in order to prevent the supply voltage [...]
