Watt 12
Watt 12 : General. The watt is a unit of electrical power. A current of one ampere flowing under pressure of one volt equals one watt. For example, a 100 watt light bulb rated at 110v takes a current of 0. 9 amp and has a resistance of 130 ohms. It is the demand for power when using items such as a light bulb, heaters, stoves, and motors that places the load on the conductors. If the demand is more than the size or capacity the conductors can carry (are rated for), heating of the conductors will follow. A fire may follow the heating or arcing growing out of the overload since circuit safety devices, such as fuses or circuit breakers may not open the circuit before ignition of combustibles occurs
