Power Factor Correction Devices Have No Impact

Caption

Power factor correction devices have no effect on a typical household electric bill because of the relationship shown here -- activating the device reduces the current drawn from a power line but simultaneously increases the power factor. Electric bills are based on the product of the two, which remains the same.
