Transformers
... The transformer is based on two principles: firstly that an electric current can produce a magnetic field (electromagnetism) and secondly that a changing magnetic field within a coil of wire induces a voltage across the ends of the coil (electromagnetic induction). By changing the current in the pri ...

... Power systems are used to convert natural energy into electric power. The frequency of electric power is highly dependent on the active power while the voltage of electric power is highly dependent on the reactive power. Thus the control issue in power systems can be decoupled into two independent ...

3–16 power factor
... Power Factor is the ratio of active power (watts) to apparent power (VA) expressed as a percent that does not exceed 100%. Power Factor is a form of measurement of how far the voltage and current are out-of-phase with each other. In an ac circuit that supplies power to resistive loads such as incand ...
