It is common to have power supply sockets installed in our homes.
I want to understand how it is measured whether it is 230 AC volt or not using multimeter.
AC supply has three terminals, Line, earth neutral. If I want to find the line in these three holes, then I can find out which line using tester. But if I don't have a tester and can't even see the wires, here's how to find out which are line, earth and neutral with a multimeter.
I don't not understand how to connect the multimeter black and red probe into the socket I know red should be connect to the line and black should be connect to either neutral or Earth. But by looking at the holes on socket, it is not known which is line, neutral and earth, so how will we identify?
Please explain the logic behind testing electrical outlets using a digital multimeter.
