For pure resistive load:PF = cos Φ = 1 resistive loadsconverts current into other forms of energy, such as heat inductive loadsuse magnetic fields like motors, solenoids, and relays Power Factor Typical power factors: Three-Phase Power Factors ...
7. The farther away the target (is), the longer time it takes for the echo to return. 8. For the series to converge, x must be less than 1. 9. We find this concept very difficult to understand. 10. This method makes it much easier to detect targets. 11. This factor will ...

Partial fraction decomposition (部分分式分解) can be written for rational expressions(有理表达式) of the form P(x)/Q(x), where P and Q have no common factors and the highest power in the numerator is less than the highest power in the denominator. Case 1: The partial fraction decompositio...
Even simpler expressions are developed for restricted ranges of conditions. The general and restricted expressions are compared with representative experimental data. The structure of the correlating equation shows why the common power-law-type equations cannot be successful over an extended range of Ra ...
Whenever an electrical machine is meant to be fed by a power converter, the design should be approached as a system optimization, more than a simple machine sizing. A great variety of electrical machines is available to accomplish this goal, and the task of comparing the different options can...
