In a hair drier, the air blows past the resistor, absorbing heat as it passes. Electric hair dryers work by blowing room temperature air in through the vents. One of the wires in this supply covered with insulation in red is the live wire (or positive), and another wire colored black is the neutral wire (or negative). These wires pass into an electric meter through the main fuse at the meter-board. The main switch, live wire, and neutral wire are connected to the line wires in our homes.
