A 1500-watt hairdryer operates by drawing approximately 10 amps from a standard 120V household outlet, utilizing heating coils designed to have low resistance. The power generated is determined by the relationship between voltage, current, and resistance, as defined by the equations P=VI and P=I²R. The heating elements in hairdryers are engineered to produce significant heat by allowing sufficient current flow while maintaining a specific resistance, unlike the higher resistance found in devices like nightlights, which consume much less power. Understanding the principles of Ohm's Law and power calculations is essential for grasping how these devices function.
PREREQUISITESElectronics enthusiasts, electrical engineers, appliance designers, and anyone interested in understanding the principles of electrical power consumption and heating elements in household devices.

(besides, pictures are a lot of work)
