Hi! I have a question related to electronics:
Someone told you that there might be a problem with the electrical circuit: In addition to the standard 50Hz alternative voltage, it mights exist another disruptive frequency at 50.5Hz.
For how long, at least, should you measure the voltage in the outlet to know if this disruptive frequency actually exists or if it is a fake information ?
The answer is 2 seconds, but I can't understand why. Can someone explain? Thanks in advance.
