The power calculation formula is: single-phase P=UI*power factor.
Calculate the safe current carrying capacity of the wire based on the square number of the wire.
Method 1: Refer to the comparison table of the safe current carrying capacity of the wire to directly see: the square number of the wire ~ the usage conditions of the wire (temperature, casing) ~ the safe current carrying capacity of the wire.
Method 2, method for estimating the safe current carrying capacity of wires.
Estimating formula:
(1) Below 10 square meters, 5 currents per square.
(2) 16 square meters, 5 currents per square. 25 square meters has 4 currents per square, and 35 square meters has 3 currents per square.
3) Copper wire upgrade counts.
(4) In case of pipe penetration, safe current carrying capacity × 0.8, abnormal temperature (generally based on 25 degrees), safe current carrying capacity × 0.9.
The cross-sectional area of wires commonly used in household circuits is: 1²-1.5²-2.5²-4²-6²-10²-16²-25²-35². The above estimation formula is based on aluminum wire, and the calculation for copper wire is automatically upgraded.
For example: 4² aluminum wire = 4×5 = 20A, but 4² copper wire ~ 6² aluminum wire = 6×5 = 30A. If 4² copper wires + pipes are laid, the safe current carrying capacity = 30 × 0.8 = 24A. If the ambient temperature is 40 degrees, the safe current carrying capacity = 24 × 0.9 = 21.6A.
After knowing the safe current carrying capacity through the above two methods, we can calculate the power that the wire can drive by the formula: P=UI.
For example: 6² copper wire calculates safe power.
It can be seen from the above: 6² copper wire ~ 10² aluminum wire, safe current carrying capacity = 10×5 = 50A, of course, you can also check the safe current carrying capacity table.
6² Copper wire safety drives power: P＝UI＝220×50＝11000W.
1 degree = 1 kilowatt hour
is: 1000 watts × 1 hour. That is to say, if there is a water heater with a power of 1 kilowatt, the electricity consumed by it when working for one hour is one degree. . Kilowatt-hour is what we usually call "degree", which is the unit of electrical power, symbol: kW·h.
Kiwatt hour is a unit of energy measurement that represents the energy consumed by an appliance with a power of one kilowatt after one hour of use, or equal to 3.6 million joules.
If the power consumption is ‘0.3 degrees/day’, then the approximate power of the refrigerator can be calculated. Calculated based on the refrigerator cooling time of 12 hours per day, 0.3/12*1000=25W. If 0.3 degrees/hour, then 0.3*1000=300W.

Assembling a computer does require a checklist, because when we assemble the computer, after determining the configuration and operation requirements of the computer, we can purchase some suitable motherboards online, and then determine the power supply, graphics card and other configurations based on the motherboard. If you ask, just make a list and ask the computer factory or dealer directly to buy it
Assembling a computer can have some benefits, such as:
1. Customized configuration: Assembling a computer can choose the appropriate hardware configuration according to personal needs, and you can choose more based on your own purpose and budget. Suitable components.
2. Cost-effectiveness: Assembling a computer is more cost-effective than purchasing a brand-name machine. You can save costs by choosing hardware with higher cost-effectiveness.
3. Upgradeability: Assembling a computer is usually easier to upgrade the hardware. The hardware can be upgraded or replaced at any time as needed to improve the performance of the computer.
4. High degree of freedom: When assembling a computer, you can choose the appearance design, color matching, etc. according to your personal preferences, and you can create a unique computer.
However, there are also some challenges and risks in assembling a computer, such as requiring certain professional knowledge and skills, choosing inappropriate hardware that may cause compatibility issues or poor performance, possible risks during the assembly process, etc. . Therefore, if you do not have enough experience and skills, or do not know much about computer hardware, it may be more suitable to buy a branded machine.
There are drawings when you buy a computer desk, just assemble it according to the drawings
1. First connect the VGA cable to the monitor, and then fix the two screws at the back. The main reason for fixing is to worry about the connecting wire falling off when moving.
2. Then connect the other end of the VGA cable to the computer host.
3. Next, connect the power cord to the monitor. (Note that you are only connecting to the monitor. Do not connect the other end of the power cord to the socket. Wait until all connections are completed before turning on the power.)
4. Next, connect the mouse to the host.
5. Connect the keyboard as well. (The green one is the mouse, and the purple one is the keyboard. Also note that the internal pins of the mouse and keyboard plugs must be aligned with the pinholes in the interface before they can be inserted.) Connect one end of the network cable to the RJ45 interface of the computer host, and then connect the other end to the switch or router or modem.
6. Next, connect the power cord of the host.
7. Next, you can connect the power plugs of the host and monitor to the sockets to power on the host and monitor. You can start and use it normally.
