    Good afternoon! It depends on what is on the other end of the cord (type of appliance). In a technique that contains an electric motor or a heater, this phenomenon does not occur (meaning the current on the plug). But if the circuit contains a switching power supply, then the voltage on the PS capacitors may remain for a certain time (up to 10 min), and this charge will remain on the plug. Computers belong to this kind of technology.

    If you touch, can it cause an electric shock?

    And another question, are the wires left to connect the sockets, etc., and if you hook through clothes, can it hit?

    Hello, tell me how to remove this residual current on the plug? Every time I turn off the sewing machine, I’m afraid to get a current discharge, although not large, but it’s not pleasant (I received it several times due to forgetfulness or in a hurry). What can I discharge the plug every time I turn it off?
