Watt 01


Watt 01 : General. (1) With ac measurements, effective power (measured in Watts) equals the product of voltage, current, and power factor (the cosine of the phase angle between the current and the voltage). Watts=EI cosine(Theta). A Watt is a unit of power that considers both volts and amps and is equal to the power in a circuit in which a current of one ampere flows across a potential difference of one volt. 2) One joule/second
