The 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.
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.
