It identifies the ratio of the direct current of equal power relative to the given alternating current. . The former can also be …
The power factor is defined as the ratio of real power to apparent power. As power is transferred along a transmission line, it does not consist purely of real power that can do work once transferred to the load, but rather consists of a combination of real and reactive power, called apparent power.
