Power leakage current
In order to reduce the interference in the switching power supply, according to the national standard, an EMI filter circuit must be provided. Due to the relationship of the EMI circuit, there is a small current to the ground after the switching power supply is connected to the mains, which is the leakage current. If it is not grounded, the shell of the computer will have a voltage of 110 volts to the ground, and it will feel numb when you touch it with your hands, and it will also affect the work of the computer.
