wever, the coil surrounds an iron core(as in an electromagnet) and alternating current is used, the powerconsumed will not be 5 kilow^atts. The power factor may be 60per cent for this coil, and the power consumed will then be SOX lOOX.60=3,000 watts or 3 kilowatts, instead of 5 kilowatts. The… … Fig. 6.
