2. One machine a day is about 0.03, 40 machines a month is 0.03 * 40 * 30 = 36, of course, 40 mining machines also need 400000, which is not included in the electricity bill.

3.

According to the current difficulty, we can dig about 0.01584 bitcoins a day. Of course, the final result of each mine is not the same, but it will be very close

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

4. There may be a problem. I can't say exactly what the problem is. You can go to the official and ask. The technical staff will let you know. It's not a problem. It may be low voltage or poor heat dissipation. Ant S3 mining machine is now in the phase out period, ant S5 has come out. Now mining relies on low electricity price and low energy consumption of mining machinery. Mining is not particularly profitable now.

5. Do not rule out this problem, perhaps you buy a try back, it is best to test the machine on site, and require an invoice, payment can be made through shengfutong.

6. ① To solve this problem, if there is 320 V voltage after rectification and filtering, then measure whether the voltage to ground of each pin of the switching power supply stabilized voltage thick mode chip is normal. If there is any abnormality, check the components around the abnormal pin of the chip, such as optocoupler, piezoresistor of sampling circuit As well as the secondary output rectifier filter elements of switching transformer
2. If the components around the above chips are normal, it can be judged that the thick die
chip is damaged.

7. Because of different brands, the design concepts of procts are different, and each has its own advantages
it is recommended to choose the right mobile phone according to the needs and preferences. Due to the large number of mobile phone models and different application groups, you can visit Samsung website to view the popular flagship models and the latest procts.

The parameters of S7 type transformer are as follows: working voltage is 220V, distribution is 1600KVA, copper weight is 20kg, silicon steel weight is 30kg, working frequency is 10kHz, working current is 500A

transformer is a kind of static electrical appliance based on the principle of electromagnetic inction. When the original coil of the transformer is connected to the AC power supply, the alternating magnetic flux is generated in the core, which is universal φ express. In primary and secondary coils φ It's the same, φ It is also a simple harmonic function φ=φ msin ω t According to Faraday's law of electromagnetic inction, the inced electromotive force in primary and secondary coils is E1 = - n1d φ/ dt、e2=-N2d φ/ dt

extended data

main parameters of transformer:

1, working frequency

transformer core loss has a great relationship with frequency, so it should be designed and used according to the use frequency, which is called working frequency

Under the specified frequency and voltage, the transformer can work for a long time without exceeding the output power of specified temperature rise

3. Rated voltage

refers to the voltage allowed to be applied on the coil of transformer, which shall not be greater than the specified value ring operation

3, voltage ratio

refers to the ratio of primary voltage and secondary voltage of transformer, which is different from no-load voltage ratio and load voltage ratio

4, no-load current

when the secondary open circuit of transformer, there is still a certain current in the primary, which is called no-load current. The no-load current is composed of magnetization current (procing magnetic flux) and iron loss current (caused by iron core loss). For the 50 Hz power transformer, the no-load current is basically equal to the magnetization current

5, no-load loss

refers to the power loss measured in the primary when the secondary of transformer is open circuit. The main loss is the core loss, followed by the loss of no-load current on the primary coil copper resistance (copper loss), which is very small
