WebPolarity in electrical terms refers to the positive or negative conductors within a dc circuit, or to the Line and Neutral conductor within an ac circuit. Electrical polarity (positive and negative) is the direction of current flow in an electrical circuit. Current flows from the positive pole (terminal) to the negative pole. WebWire up a LED + 1K ohm resistor like the image below: Note the polarity of the LED; the flat side of the LED is negative. Polarity of resistor doesn't matter. Now connect the other end of the resistor (top of the diagram) to the center conductor and the LED flat side wire to the outer conductor of your adapter.
