statwattThe statwatt (symbolized statW) is the unit of power in the cgs (centimeter/gram/second) electrostatic system. In a direct current ( DC ) circuit, 1 statW is the power dissipated, radiated, or expended when one statvolt (1 statV) of potential difference drives a current of one statampere (1 statA) through a component. In a DC circuit, or in an alternating current ( AC ) circuit in which there is no reactance , the following formula holds: P = EI where P is the power in statwatts, E is the potential difference in statvolts, and I is the current in statamperes. The statwatt is a small unit of power, equivalent to 10 -7 watt (W) or 0.1 microwatt (µW). In most applications, the watt , which is the unit of power in the International System ( SI ), is preferred. Also see power , watt , cgs or small-unit metric system , and International System of Units ( SI ).
