 * Note: For calculation purpose, zero (0) value for these components, are interpreted to mean "not in circuit".





POWER FACTOR CALCULATION

Generally, it is desired to have a power factor as close as possible to unity(1). At this value the current will be the lowest, and the Volt-amperes demand will be the lowest.
