Capacitors insertion reverse can be detected by image recognition or ICT For capacitors with polarity, such as electrolytic capacitors, tantalum capacitors, etc., it is absolutely not allowed to plug them in reverse. If they are plugged in reverse, they will soon fail or even burst. In the production of circuit boards, it is very necessary to [...]
Several sources in Germany revealed to the media on the 10th that the German government will stop providing free new crown virus testing to all people from October in order to further promote the new crown vaccination. German Chancellor Angela Merkel met with the heads of 16 state governments across the country on the same day [...]
A single-phase motor with a slightly larger power is generally equipped with two capacitors, namely the starting capacitors and the running capacitor. Before 70 years, single-phase motors were mostly a capacitor, which is a starting capacitors. After the motor is started, the capacitor is thrown off by the centrifugal switch, and only the main winding works [...]
Xinhua News Agency, Washington, August 2nd. The International Monetary Fund (IMF) stated on the 2nd that due to the impact of the new crown epidemic, the scale of global current account imbalances in 2020 will increase from the previous year, and it is expected that the scale of imbalances will further expand this year. The IMF [...]
A parallel plate capacitor is composed of two parallel metal conductor plates, separated by a dielectric material in the middle. When there is a certain potential difference between the two plates, there will be an electrostatic field distribution between the plates. There is a uniform electric field distribution in the part between the two plates. Due [...]
