black wire with white stripe
In the Technology section, to the question 2 wires come out of the power supply. Both are black, one has a white stripe. Which one is “+”? asked by the author Prosyanka the best answer is with a white stripe+
, then: you need to use an indicator screwdriver; on which wire the light bulb in the screwdriver lights up, this is the phase - “+”, on which there is no - ground, “-“. If -constant-, then: connect a digital multimeter (voltmeter) to both wires, and if it does not show the symbol “ -“(minus), this means a direct connection, and here it’s not difficult to guess which is minus and which is plus (the wire to which the red wire of the multimeter is connected is “+”) PS. In general, black usually means zero (minus), and the other (usually red) means plus, but who are these Chinese if the power supply is Chinese?
