It's not that the electrons don't fall to the nucleus, but typically they don't fall to the nucleus, otherwise the atom is too unstable. But under the right conditions, electrons can fall to the nucleus, but it takes a lot of energy. Here's a layman's explanation of why this is so. First of all, say the scientists study atomic model, which the rutherford model "planet" a representative, he through the alpha particle scattering experiment demonstrated that most of the atomic … Continue reading "The electrons are negatively charged and the nuclei are positively charged. Why didn't the electrons fall into the nuclei?"
A netizen commented that the same phone, Samsung Note9, saves battery power far more when plugged into the mobile card alone than when plugged into the Unicom card alone. Online, wifi is also used in this case. This IS THE BATTERY LIFE OF THE MOBILE CARD INSERTED YESTERDAY AFTERNOON UNTIL 8:20 AM TODAY. Besides SCROLLING news, XIMalAYA LISTENING has been busy, and it still HAS 68% battery LIFE. If that was the case with the Unicom card, it would have … Continue reading "Use mobile phone card, save electricity more than Unicom telecom card?"
Hardware FITTINGS IS THE SMALL HARDWARE THAT SHOWS METAL TO PASS THE PROGRAM SUCH AS STAMPING TO MAKE AND BECOME, WAIT LIKE GASKET, RIVET, BUTTON. These hardware products are widely used in all walks of life, people's production, life. What are those areas? First, clothing bags The buttons and rivets in the hardware accessories are mostly used in the clothing luggage industry. For example, the buttons on jeans, metal accessories or joints on bags and bags, the requirements for such … Continue reading "What are the application areas of hardware accessories?"
Scientists have long predicted that electrons can flow like water, but this behavior has never been observed. Now, Israeli scientists report in the latest issue of the journal Nature that they have observed this strange behavior for the first time, in a new study that could lead to low-power electronic devices. Professor Shahar Irani, of the Weizmann Institute of Science, said: "Theory suggests that liquid electrons can do things that other types of electrons cannot. But to get clear and … Continue reading "Seeing is believing: Electrons really do flow like water"
With the rise of artificial intelligence, intelligent chips have been developed vigorously in recent years. Compared with traditional chips, smart chips are larger in scale, more complex in structure and more powerful in computing power, which can provide new technical support for complex intelligent processing requirements such as large data volume, multi-task and high throughput. Now intelligent chips have been widely used in image recognition, speech recognition, intelligent driving, intelligent security, consumer electronics and other fields. At present, there are … Continue reading "What are the well-known smart chip brands on the market"
A dc voltage regulator power module consists of four parts, respectively is the transformer, rectification, filtering and voltage regulator, about the transformer, rectification, filtering, in the previous article has been roughly introduced, also a voltage regulator, this paper focuses on the regulator circuit. The circuit through the voltage regulator, the output waveform can be basically constant, which is in line with our expectations, the realization of voltage regulator, is determined by the characteristics of the regulator element. A voltage regulator … Continue reading "Dc regulated power module"
I believe that we are not unfamiliar with diode, on two legs, perhaps, engaged in electrical professional you can see it every day. Diode has two legs, a Yin and a Yang, the anode is a, the cathode is K, pay attention to its drawing and marking, wiring do not make the wrong polarity, or there will be a big mess! Some diodes are marked on the body, not marked, there are packaging symbols, with a silver ring for the … Continue reading "Talk about diodes"
In Intel, Taiwan Semiconductor, Samsung previously strongly appealed to the US Congress to pass the chip Act, to provide $52 billion in funding subsidies, the news pointed out that the US Congress has decided to vote on the bill on Tuesday. Senate Majority Leader Chuck Schumer said the U.S. Congress could vote as soon as Tuesday on a bill to finally support the recovery of the U.S. semiconductor industry, Reuters quoted sources as saying. However, because the bill is only … Continue reading "Building a factory in China without subsidies! America's huge $52 billion chip law subsidy may be set up"
Chip testing is divided into two types, one is wafer testing, also known as CP testing, also known as intermediate testing. As mentioned before, after the wafer is manufactured, the electrical performance and circuit function of each chip on the wafer are tested to ensure that the wafer can realize the circuit function of the chip, and then sent to the packaging factory for packaging. The other is the finished product test, also known as FT test, which is to … Continue reading "What kinds of chip tests are there?"
We know that power devices are the core of electric energy conversion and circuit control in electronic devices. They change the voltage, frequency, phase and DC/AC conversion functions in electronic devices by using the characteristics of unidirectional semiconductor conduction. Power devices are divided into many categories based on controllability and other usage factors. Common classifications include: MOS Controlled Thyristor (MCT) MCT is a new type of MOS and bipolar device. MCT is the MOSFET high impedance, low drive MCT power, … Continue reading "What are some common power semiconductor devices?"
