For a rotational system, it is torque times angular velocity, or it can also be computed as the dot product of force and velocity.
In an AC circuit, the ratio of resistance to impedance gives this quantity's namesake factor. For an electromagnetic wave, this quantity per unit area is described by the Poynting vector, which gives the wave's intensity. In a circuit, this quantity is equal to current squared times the resistance, or alternatively current times the voltage dropped. For a rotational system, it is torque times angular velocity, or it can also be computed as the dot product of force and velocity. For 10 points, identify this quantity measured in Watts, which is equal to the work done over the time.
