what is the 400v capacitor for? In the PC power supply?

Answer 1

After rectifying the mains (effective value 220V) voltage (after the diode bridge), this capacitor serves to smooth out the ripples and charges up to about 310V (the amplitude voltage in the network, remember the sinusoid). I understand that in the line of capacitors, the nearest suitable voltage is 400V.

Answer 2

1) Where in the food chain is it located?
2) What actually confuses you? This is the upper voltage ceiling.

Answer 3

To smooth out pulsations.

Answer 4

It's easier in one because there are a finite number of schools.

Answer 5

If the data of all schools fit into a common data structure, make one database. If there is a lot of data in the future, consider mysql partitioning.
